International ClassA61N 001/00AbstractA bio-operated implant system for implantation inside a human body. A piezoelectric generator in the form of a flexible sheet of poled polyvinylidene fluoride structurally that is attached in surface-to-surface contiguity with a skeletal number, which flexes with negligible elongation of its surface, is connected in circuit with a power consuming device such as a pacemaker, to a rectifier, and to a power storage device such as a condenser or battery. The generator generates in alternating voltage, which is rectified to direct current, which is supplied to the power consuming device on demand.Other References
