Bioimpedance Spectroscopy Boards Arrived
I had some PCBs made up to do some bioimpedance spectroscopy for edma detection through the cole-cole model. One set has an MCU & space for a bluetooth module meant to communicate with an android tablet. The other is a stand-alone module that I’m going to try and interface directly with a microtouch avr touchscreen.
These will go from 1kHz to 100kHz. If you notice the big PCB, I made the VIAs have a teardrop shape – they look cool. It’s based on my design for a fixed 50kHz device for impedance plethysmography that I use to measure respiration. Fun stuff!
