What is piezoelectric transducer?

According to, electronics-manufacturers.com/products/s... ----quote---- Piezoelectric transducers have been conventionally used to convert electric signals into sound waves or other mechanical vibrations, or to convert mechanical vibrations into electric signals. A piezoelectric transducer includes a vibrating piece which has on both its surfaces electrodes for providing an electric field to the vibrating piece. The piezoelectric transducer converts electric signals into mechanical vibrations or vice versa by utilizing the morphological change of a crystal which occurs on voltage application, or conversely by monitoring the voltage generated by a pressure applied on a crystal.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
