Abstract

A device for optimizing transmitting energy and transmitting position for an implantable electrical stimulator is provided. The device utilizes a design of a wireless energy transmitting and positioning device with an external energy-feedback control, which can automatically detect an optimum energy-transmitting position through an external antenna performing an adjustable energy transmission method, and through a wireless-feedback control method to provide the optimum energy. As such, the implantable electrical stimulator can exactly and effectively stimulate the nervous muscle.
