Hi everyone, I am working on a project for school that I need some advice on. It will be a medical device for anesthesia monitoring. A patient will have one of these sensors attached to their thumb (force, flex, accelerometer or pressure). Most likely we will use force or flex sensor. A current will then be applied to the ulner nerve (wrist area) which will then stimulate muscle movement of the thumb. Based on how much muscle movement you have, you can figure out if the anesthesia medicine is wearing off or there is too much of it. The goal is to monitor the muscle movement and display the data on a display in form of a graph. The way the current pulse works is you have 4 pulses in 2 seconds (so one pulse each 1/2 of a second). I am not exactly sure how often we would need to sample the sensor data to recover the correct graph. I just need your advise with the sampling rate and what would be the best microcontroller for the job. Any help would be much appreciated. Let me know if you have more questions.
