Energy Transmission Through Intact Skin.

摘要

The report covers research directed toward the development and application of a technique for transfer of electrical energy into the body in sufficient quantities to operate an implanted artificial heart. Progress was made in reducing the size and weight of components,especially those to be positioned near the heart within the thorax,without loss in overall efficiency. Progress was also made in upgrading the external power system to more nearly represent a truly portable system with increased reliability. A detailed analysis of motor performance was made including the effects of viscosity in submerged operation. Computer programs were developed that make it possible to determine the optimum gear ratio and motor winding voltages,given any combination of system losses,loads,and supply voltage.
