Capacitance simulations with a hand/finger
Posted: 20 Apr 2023, 23:10
I am looking to simulate some electrodes and how introducing a human hand affects the capacitance of those electrodes. I've been using Elmer's electrostatic solver to do so currently but I was wondering if someone could point me in the right direction for my simulations. I am mainly wondering if this is the right solver to be using and if Elmer is capable of simulating such a system.
My main goal for this simulation is to find the difference in self-capacitance for each electrode with and without a hand introduced to the system nearby. I am wondering if there is any way to differentiate using a finger vs a metal cylinder in simulation as my eventual goal would be to physically test with a standardized metal cylinder and compare with the simulation to verify my findings.
I've also looked into the Human Body Model (https://en.wikipedia.org/wiki/Human-body_model) and I was also curious if there was a way to define and incorporate an object with a set capacitance of 100pF.
