Sensor for measuring time a subject Answered

I would like to have a thin sensor that can measure the wearing time of a hand brace of a patient? Any suggestions? Some people call it compliance sensor and using temperature during time. Thank you


Just use a thermistor bead. They're as fine as pinheads. Then all you need to do it monitor the resistance, and measure when it goes into/ out of body heat.

You could POSSIBLY do it by measuring skin resistance too.

What you are looking at is a temperature sensor for body heat, datalogger with time stamps, and possibly an accelerometer to determine hand position. You can get arduinos in small form factors and design with small electronic components to get it altoids tin can size or smaller. Good luck.
