Abstract
A biological transducer device for measuring blood pressure, heart pulse, heart sound etc. comprising a high molecular piezoelectric element which is in a thin film or ribbon form so that the transducer is very pliable so as to make close accurate contact with a measuring point on a human body without producing any creases. The piezoelectric element is enclosed in netting comprised of a metal wire mesh so that the transducer is completely shielded from outer mechanical and electrical noise.
