Summary

Bioamplifier based on a Raspberry Pi Zero w that streams data to matlab. The project was made at the NIFTy group at the University of Twente as a demonstrator for the IEEE student measurement challange at the IEEE conference in Glasgow in 2017.

How I Designed This

The band contains a custom made bioamplifier and a Raspberry pi zero w to strain the data to a PC running Matlab via WiFi. The code and the schematics of the amplifier are available on: https://github.com/martijnschouten/raspberry-bioamplifier.

Cad drawings are made using Fusion 360.
