Abstract: The present invention relates to an implantable nerve stimulation device, which includes: a body part which is formed of a metal that ultrasonic waves can be transmitted, and includes a stimulation surface and a charging surface facing each other; a header part which is made of a non-metal and is located at one end of the body part; a cover which includes a stimulation electrode, a hinge part rotatably coupled to one side of the stimulation surface, and a coupling part detachably coupled to the other side of the stimulation surface, is positioned above the stimulation surface to interpose a nerve between the electrode and the stimulation surface; and power generation elements which are located inside the body part and are electrically connected to the electrode.

Abstract: The present disclosure relates to a medical ultrasonic triboelectric generator structure for charging a body implantable device and a method of forming the structure. A method of forming a medical ultrasonic triboelectric generator structure for charging a body implantable device includes (a) primarily performing a plasma process on a power generation material on which a polymer material is disposed and performing bonding of the polymer material and a non-conductive material, and (b) secondarily reinforcing the bonding using a physical guide structure including a non-conductive guide structure and a fixing coupling structure.
