Medical pressure sensor

fun / internet of things

Alix (Alex’s girlfriend) is intern in surgery. For her PhD, she wants to prove that the cochlear canal is porous. Therefore she needs to be able to measure hydrostatic pressure simultaneously and precisely in different points of a dead body.


Since the professional tooling to achieve this is out of reach, and that she is not 100% sure about the validity of the experiment, Alex decided to craft a little solution based on Arduino.


The result is small, effective and inexpensive (about 30 euros) and works with usb on any laptop hence to the arduino toolkit. Besides Alix thesis, it was a good excuse for Alex to learn SPI and I2C protocols.
