this is more of a theoretical question, and I do not know if this is suited for this QA site at all, but at school I was asked to provide 3 examples of sensors (in the narrow sense) that are also actuators.
I cannot find any information for the life of me. The only example I can find are piezoelectric sensors, but I am not sure if this is correct.
A sensor in the narrow sense is a device which reacts to a signal/stimulus from a electrical signal.
