| This chapter presents the state of the art, meaning the highest level of development of a technology, art, or science. In this chapter the Team will explain what a UV meter indicates and includes the research on several existing products on the market containing its functions. They first had to discover what kind of wearable UV meters already existed on the market and understand why they are attractive to the user. There are thousands of wearable UV meters, only on Amazon there are already 4398 UV meters purchasable. Analysing all the different wearable UV meters would be impossible. The Team has chosen 5 popular wearable UV meters which they compare by pointing out their advantages and disadvantages. Furthermore, variables the competitors use to give personal based advice on protection for the customer. Finally, the Team focuses on the different materials that were used and the materials that will suit our device best. Considering the research done, the Team came to a final conclusion on how the design of the wearable UV meter and final prototype should look. | This chapter presents the state of the art, meaning the highest level of development of a technology, art, or science.

| | Test 3 was the final test before soldering all components on the PCB board. The code is working as it the Team wants it to. Tests were made on the 16th of June, at 9 o'clock in the morning when the UV radiation level, according to the weather forecast was 3, as can be seen in Figure {{ref>test3}}. The green LED and the buzzer go on when the Sun is not coming right at the sensor. When the Team turns it right at the Sun, the UV radiation goes up to 3.77. This means the yellow LED goes on and also in the same time as the buzzer. When the button is pressed the reset function goes on, and gives immediately the latest highest value. It signals with both the corresponding LED and the buzzer. The values from the test can be seen in Figure {{ref>valuestest3}}. |

| //"The device needs to be put into salt and fresh water for at least an hour and one meter deep. Afterwards the device should be tested to be sure that it will still work properly".// That were the requirements the Team had for the waterproof test, they realized they will see if the device is waterproof when the device is under any water, it does not need to be one meter deep. The Team made the waterproof test in the bathroom sink. They put the device down so it was fully covered with water. They put a piece of a cotton pad inside to easier see if the water will come inside. The cotton pad were used instead of the real electronical components, in case it would not be waterproof. The device have an O-ring as a packing so the water would not get in between the two parts of the device. The result can be seen in Figure {{ref>waterproof}}. The device was not waterproof, a change could be to have a thicker O-ring. Even though the device would have been waterproof now, it would not be that when the holes for the LEDs, sensor, buzzer and button are made. More development are required to figure out a new solution. | //"The device needs to be put into salt and fresh water for at least an hour and one meter deep.

| The requirements for the wearability included two things: The device could be worn both as a bracelet and a clip-on. The Team have the bracelet with Velcro, so the size can be easily adjusted. Magnets are used so it can easily be changed from a bracelet to clip-on and vice versa. The clip on is made with a band of silicon and also with magnets, so the user can clip it on wherever they like. How the bracelet can be used can be seen in Figure {{ref>bracelet}}. Example of the clip-on wearability can be seen in Figure {{ref>clipon}}. The result from the wearability test is that the device can be worn as both a bracelet and a clip-on. The size of the user do not matter, because of the Velcro. Due to cowardice, did the device not be made in time so it could be worn on different people for over a week, as the Team said in the beginning of the project. | The requirements for the wearability included two things: the device could be worn both as a bracelet and a clip-on.

| The prototype itself can be dropped without breaking from 1.20 meters height. The Team made the robustness test by putting a piece of a fragile TUC cracker inside the cork block. Then they dropped the cork with the cracker from 1.20 meter height, and the cracker did not break. The Team do not recommend to drop it with the electronical components inside, because the components will come on the outside of the box, and then they may break. How to protect the outer electrical components needs future development. | The prototype itself can be dropped without breaking from 1.20 meters height.

This is also a way to attract new consumers by an original shape, or colours. This is the last step in a product development. |
| |
| There are different types of packaging: primary, secondary, and tertiary. The primary packaging is the first wrapper; it is in direct contact with the product. The secondary is the sales unit and sometimes it regroups products by bundle. It also has the role of attracting consumers and informing them about the brand, the product itself and benefits for the user. The tertiary packaging is the logistic unit. Sales units are gathered together, in cardboard box called regular slotted container (RSC) if the product itself is small, then put on pallet and wrapped with plastic film. That type of packaging facilitates transport between firm and stores. | There are different types of packaging: primary, secondary, and tertiary.

| Packaging is everywhere and brands use it to get more consumers by creating new shape and design. Nowadays, with the sustainable development, packaging should be recyclable and even biodegradable. Ecology is in every mind so designers must build a package with the less environmental impact as possible. In this way, the Team looked for a reused or recyclable material, keeping the high quality of the concept. | Packaging is everywhere and brands use it to get more consumers by creating new shapes and design.

| In order to stay in an ecology process, the authors made the choice of creating the packaging in an ecological material. First, the Team thought about cork and wood, but it would be too difficult to manufacture and the device itself is in cork. They finally agreed to develop a packaging in cardboard: easy to eject, cheap and environment friendly. | In order to stay in an ecology process, the authors made the choice of creating the packaging in an ecological material.

| There are three types of cardboard: folding, compact and corrugated cardboard. Type depends on thickness and form. Raw material are trees transformed in paper pulp, used to make paperboard with different grammages (paper weight by squared meter). | There are three types of cardboard: folding, compact and corrugated cardboard.

| * Corrugated cardboard is made of liner or layer (inner and outer) and flute inside, in brown paper. It exist different name of corrugated cardboard determined by the size of the flute and many combinations of fluting are possible, as is presented in the Figure {{ref>labelpac1}}. With the grammage of paper used, it influence on the cardboard strength. Those varieties of cardboard are used for large or heavy products. There are also employed in logistic, mainly in the regular slotted container, which is a standard box. | * Corrugated cardboard is made of liner or layer (inner and outer) and flute inside, in brown paper.

| After those firsts drawing, the Team consider the marketing plan, namely the quality of the device, selling point, and the price of the product to decide on the packaging shape. Indeed, the packaging price does not exceed 10% of the final price. In the marketing part of Helios, the Team estimated around 100-150 € the price of the device. That is why, the maximal cost of the packaging process is 12 €. That seems huge for cardboard, but there are also to consider manufacturing and modelling process, shipment and storage. | After those firsts drawing, the Team considered the marketing plan, namely the quality of the device, selling point, and the price of the product to decide on the packaging shape.

| Additionally, in an ecology context, the quantity of cardboard and of glue points must be taken into account. In packaging language, the quantity of cardboard determines the amount of cardboard (blank and waste) required building a box. Thus, the Team studied each solution. The first simple box and the drawer box needed two pieces blank, with on each one four glue points. The third proposition is constituted of one blank which fold on itself, so it need many glue, and two magnets (or a tab). The last box is made of one piece blank, with five points of glue. In this way, the Team retained the latter to develop on the next part of this report. | Additionally, in an ecology context, the quantity of cardboard and of glue points must be taken into account.

| Once the solution chosen, the Team had to create the blank which needs to perfectly fit with the wedging and the device size. With this aim in mind, the Team worked on a software called Picador to draw the pattern of the box with in real size. A blank is constituted of cut lines, in red, and fold lines in blue. Drawing process include modifications to improve the final quality and design of the packaging, as it is presented below. The first idea, in Figures {{ref>labelfig1}} and {{ref>labelfig2}} was to close the box as the tea or chewing-gum box. But the Team found this enclosure system gave a poor quality image of the device. That is why, the system has been change as it can be seen in the Figure {{ref>labelfig3}}. To protect the device as much as possible, it is necessary to add a wedging inside the box. The blank, presented in Figure {{ref>labelfig4}}, shows two holes for accessories and one place for the device. | Once the solution chosen, the Team had to create the blank which needs to perfectly fit with the wedging and the device size.

| Team Helios reviewed this semester abroad. First of all, working as a team forced the members to divide tasks and have trust in each other. When people are in their professional life, they do not know with whom they will work. This was the same for these students, as they came from five different countries, have five different mother tongues and backgrounds on education. The team members learned from each other and moreover learned about themselves. Within the EPS, they also discovered a new country with its own culture and traditions. Participating in several events, visits and travelling around was a part of the learning progress and staying open-minded. Finally, team Helios was glad to live this amazing adventure, and work on this project. | Team Helios reviewed this semester abroad.

| The Team was able to work together, gather the knowledge required to address the problem, decide on the requirements, design, materials and components, assemble and test a proof of concept prototype as well as produce the set of mandatory deliverables. The Team have now made a UV meter that is showing the UV radiation level by lightning up five different LED lights (one color represents one level) and gives sound from a buzzer when the level is changing, as the Team stated in the objectives. The device can be worn as a bracelet or used as a clip-on. The two things missing is an application, and the on and off function for the button. Lack of time, budget, and knowledge are three of the reasons why an application was not made. The Bluno Beetle had Bluetooth built in, but it had problems with connecting it to the computer and the applications that were already made. Eventually the Team managed to solve this problem and successfully connected the device with the computer through Bluetooth. The reason the on and off function is not working, is because you can’t turn of the Bluno Beetle without a power switch. The Team got aware of that problem in the end of the prototype building process, when it was too late to do anything about it. | The Team was able to work together, gather the knowledge required to address the problem, decide on the requirements, design, materials and components, assemble and test a proof of concept prototype as well as produce the set of mandatory deliverables.

The Team got aware of that problem in the end of the prototype building process, when it was too late to do anything about it. |

| //Elin Lönnqvist//: Going on exchange is something everybody should try, you will develop yourself and become more secure. I have also learned to work with people from different countries with different cultural personalities. To learn languages is important for me, and it is something that I will use in my future working life. This semester I got the ability to improve my English and learn some Portuguese. The EPS semester was not really what I expected, I thought I were going on a 4.5 months vacation in a warm and sunny country. Well I was wrong… It was more school than I expected, and Portugal was not that warm and sunny as I thought. The project was interesting and I could not ask for lovelier team members. For future EPS I hope there will be a better explanation what kind of skills is needed for every project, before choosing it. A little bit less programming and electronics in the projects would be nice. And hopefully another solution to wikipage is found, now much extra and unnecessary work is made due to that website. Overall I am glad I took the opportunity and went on an Erasmus, but I hope the EPS@ISEP will listen at the feedback and think about them so the next Erasmus can enjoy their semester even more. | //Elin Lönnqvist//: Going on exchange is something everybody should try, you will develop yourself and become more secure.

| //Marion Cullié//: This semester abroad was a rewarding adventure and I enjoyed each moments. Thanks to this EPS, I worked in a really cool international team with different backgrounds as in a future professional environment. This allowed us to develop our skills and learn new knowledge. Also, live in a foreign country, discovered a new culture and travel around beautiful landscapes gave us so many memories. Finally, I can say that I have grown from this experience, I could improve my English, learn from this project, from the others and about myself. | //Marion Cullié//: This semester abroad was a rewarding adventure and I enjoyed each moments. Thanks to this EPS, I worked in a really cool international team with different backgrounds as in a future professional environment. This allowed us to develop our skills and learn new knowledge. But there are some bad points which slowed us such as later feedbacks and the use of the wiki page. However, it was incredible to live this foreign country, discover a new culture and travel around beautiful landscapes. Finally, I can say that I have grown from this experience, I improved my English, learned from this project, from the others and about myself. |

| //Simone Smits//: I am thankful for having the opportunity to participate in the EPS at ISEP, it was was an amazing experience to be in Porto learning many new things and meeting new people, while discovering Portugal and its culture. Within the EPS I improved my soft skills and broadened my knowledge, but the project was very technical and I could not apply a lot of my study like I hoped to. Also the organisation was not always that great and clear like I am used to. I did had a great team and I am glad we successfully made it until the end together. | |

| //Mikk Tootsi//: During EPS I learned a lot, especially in the field of electronical engineering. It was my first time writing a code and I`m really glad that finally after many hours working on the code it was working correctly. Working in a multicultural team was a really good experience. Our team was working together perfectly! I liked Portuguese, communication and project management classes. I’m thankful for this opportunity and ISEP also I want to thank all the supervisor and teachers who really came and helped us out with our project! | //Mikk Tootsi//: During EPS I learned a lot, especially in the field of electronical engineering.

| But there was also a lot of negative. I feel that most of the module classes did not taught us anything useful, they were really basic and started to repeat themselves. We lost a lot of time where we could have just focused on the project. I was hoping that we will finish the project much earlier and can enjoy our last days here in Porto but we are still working on the project even after the final presentation. I have heard that the EPS in other countries has nothing to do with electronics but here all the projects include building and electronical prototype and writing codes. Don’t get me wrong, I prefer the more applied EPS but the bad thing is that there was only one person in the whole EPS group who had experience with electronics and coding and here we only had two classes on Arduino, which were also really basic and too early in the semester. There should be more classes on electronics and coding also after when the components are received. I also didn’t like that we only received the feedback on Thursday meetings even if we already saw the supervisor during the week. I would prefer that the teachers/supervisor would have visited us more in the class, that way we would have received the important feedback and help on time and we would have worked more efficiently on our project and made better prototype. | But there was also a lot of negative.

| It can be concluded that developing a wearable UV meter is very important, namely to make people aware of the rising risk of getting skin cancer, because the ozone layer is decreasing due to the climate changes. To improve the Helios device the Team made some recommendations for future work: | It can be concluded that developing a wearable UV meter is very important, namely to make people aware of the rising risk of getting skin cancer, because the ozone layer is decreasing due to the climate changes.

| For the future development the device should be smaller, with a better organisation of the components and a plastic case (PET for example). The bracelet and the clip on should be in TPsiV because of its skin contact. Also a mobile phone application should be made. It should give all the information the user needs, including personal based protection advice. Hereby the idea is that the user can make a picture of their skin and send it to the mobile application which will have a database with many types of skin colors. The mobile application also includes alerts on underexposure and over-exposure to UV radiation, and when the user should reapply sunscreen with a certain level of SPF. | For the future development the device should be smaller, with a better organisation of the components and a plastic case (PET for example).
