Hand-held Neurothesiometer

More background information on what a neurothesiometer is, why this device is different, and how to operate it can be found on the following page.
Hand-held Neurothesiometer – What, why, and how?

This project started initially as a group project named “Electronic Tuning Fork” for Undergraduate Senior Design in Fall 2017 and Spring 2018. Later, I returned briefly on the project while working at Prof. Yang’s Lab and revised the circuitry, as well as designed a PCB based on it .

My roles during the initial group project:
• Design the initial circuitry
• Test the circuit on breadboard
• Program micro-controller
• Build testing program with LabView and NI myDAQ (a data acquisition device)
• Iterate circuit design

Circuit schematics

These schematics were drawn using NI Multisim version 14.1.
