AD5933 Arduino Serial Monitor Interface

If you don’t happen to have an Android phone, or an Android phone that has BLE support and you still want to work with Analog Device’s AD5933, I’ve written an Arduino sketch that allows one to interface with the AD5933 through the serial monitor on a hosting PC.

The sketch is available here.

Have fun!

Extracting Bio-impedance Parameters from Measured Data

First post of the new year! I figured, I’d start with something interesting.

Over winter break, I went home to the lovely warmth of West Africa, and had an epiphany of sorts as to how to extract the resistive values for intracellular water (ICW), extracellular water (ECW) and the capacitive value for the cell membrane after performing a frequency sweep on biological tissue (or model circuit) of interest.
