Ideas to detect when someone is trying to detach an object firmly attached?

if a moderator can please move the topic to General discussion since I could not

My question is: I'm designing a tracker for assets. I want your suggestions to implement into the circuit a method to detect when someone is trying to remove the tracker. I was thinking of surrounding the board with touch pads all around the edges of the board but I guess that would be very sensitive to noise and electromagnetics since the device has antennas and receivers.
