Hi, I'm a physics student from Nigeria and I'm interested in doing a project involving piezoelectric transducers. The project will deal with how a piezoelectric material can produce voltage from the mechanical stress of a human footstep, so my first question would be how and where can I find (buy) a piezoelectric transducer (plate) that can withstand the weight of a footstep and is not so sensitby nikoTesla - Experimental and Hobby
