PSS Health & Sport

Group portfolio

This website was created during the course Extreme PSS Innovation and in this portfolio, we will show the different steps of the process, from needfinding to MVP.

About

to About

In the last decade, wrist-worne technology for measuring various health variables has increased sharply. In the early 2010s came the first activity bracelets such as the Nike Fuel Band, Jawbone Up, and Fitbit Flex, which were primarily pedometers. In 2015 came a whole new generation of smart watches, such as the Apple Watch, Microsoft Band, other versions from Fitbit and Samsung. The big difference was that they used LED lights (photoplethysmogram, PPG) to measure, among other things, heart rate.

The goal of this project is to devise a possible measurement that would be valuable for improving health. It can be either for patients in hospitals, in geriatric care, for prevention / detection in the population, or for optimization of sports performance. Then create an MVP (minimal viable product).

Christoffer Fors

Hi! My name is Christoffer and I'm a mechanical engineering student. Because of my great interest in technic and product development I have chosen to focus my education on sustainable product development.

Mohammed Ali Hussein

My specific work filed is Sustainable Product Development. The main goal for most of my projects is to create sustainable and creative solutions. Innovation is key to entrepreneurship. I have worked in different work fields and have gained a lot of experience, yet there is much more to learn and expand. Some of my strongest skills are the ability to work with different teams, analyzing and solving problems.
