To only measure tremors in the hand/wrist, I used a
Adafruit 4485 Adafruit LSM6DS33 + LIS3MDL - 9 DoF IMU with Accel/Gyro/Mag - Stemma QT Qwiic
mounted on a Velcro strip.
I recorded the data using a ELEGOO MEGA R3 Board ATmega 2560 and a Seeed SD card shield.
The software I used was exFat SD data logger and the Adafruit library for the sensor.
This will not run on an Uno as there is not sufficient ram.
