I sewed a belt for the Master's project of a fellow student. His project explores the importance of dreaming in waking life and
therefore he wants to measure body signals while a person sleeps to represent that data in waking life.
The belt measures the wearer's respiration, movement, temperature and heart rate.
To house all these electronic components, I made pockets inside the belt which can be opened to access the components and even have see-through windows. I also made all the soft circuits with conductive thread inside the belt so that it is soft and comfortable to wear: Sewing the status LEDs on the outside and the different sensors on the inside and outside. Creating a good solution for the on/off switch and the sensor that recognizes when the belt is worn was particularly challenging.
