I need to measure the AC voltage on the surface of a plate (plate x) without making any direct contact with it. In theory I should be able to take another metal plate (plate y), secure it some distance above the plate x, and measure the induced voltage on plate y.
Is this feasible in reality? All of the "wireless" sensing methods I have came across are fairly expensive, this seems like a simple and cheap solution if I do not require high precision measurements. I understand the dimensions of plate y and the distance between the two plates would have to be optimized.
Any thoughts? I appreciate any and all input. Thank you.
