1. A piezoelectric, electrical energy generator comprising first and second supports, a first piezoelectric power generating element mounted between said two supports for being variably, elastically strained along an axis intersecting said two supports, means for causing one of said supports to circle relative to the other of said supports for causing substantially continuous variable straining of said element in response to continuous relative circling, said first element being one of a plurality of substantially identical elements all of which are secured between respective first and second supports all mounted for causing identical circling movements of each of said first supports relative to respective said second supports for continuously variably straining all of the elements, each of said power generating elements comprising an elongated strip of electroded piezoelectric material secured between said supports, and said elongated strip being folded to form a loop having two free ends and a bight intermediate said two ends, said bight being engaged with said first support, and said two free ends being secured to said second support.
