Building a heart-rate sensor with Richard

Date: 20-06-08, present: Danielle & Richard van Bemmelen I asked my friend Richard to look at the instability of our current heart rate sensor. Richard is a programmer and engineer so exactly the right man for the job 🙂 It was kind of hard to analyze the current device as everything was soldered together. But […]

Meeting June 6 2008 in Breda

Report of the meeting at Danielle’s place in Breda from 11 to 15 hours, 06/06/08. Present: Anja, Barbara and Danielle. Ideally we want to do the sensing inside the material and not with separate sensors. There is sensitive foam which responds to stretching and pressing. It is used to measure breathing, shoulder movement and shoulder blade […]

Heating

I’ve done a little research into heating elements. As stated in the book ‘Pysical computing’ the firm Minco has a wide range of heat sensors and elements. Interesting are the flexible sensors and elements. Both come in very small sizes. The sensors can measure very small temperature differences, I’ll seen numbers like 0,04C. Here’s an example: Polyimide […]

We may use some of the underlying theory […]
