经皮能量传输系统（TETS）在9个小牛实验中被用于为宾夕法尼亚州立大学电机驱动的心室辅助装置提供动力，总共累积了316天的体内经验。这被认为是迈向完全植入式心室辅助系统和全人工心脏的重要一步。TETS通过电感耦合将外部12伏直流电源转换为可调节的14伏输出电压，供电机控制器使用。最大输出功率为70瓦。在小牛实验中，TETS的平均输出功率在8到12瓦之间。在这些实验中，电机控制器没有植入，等待微型化电子设备的进一步发展。TETS输出经皮返回到外部电机控制器，允许直接监测TETS输出。系统效率，从直流电源到直流输出，包括12英尺电缆的损耗，范围从55%到%，取决于电源电压，电机负载和线圈耦合程度。皮下线圈耐受性良好，仅表现为暂时性、轻度、浅表硬化。
A transcutaneous energy transmission system (TETS) has been used to power the Penn State motor driven ventricular assist device in nine calf experiments, for a total of 316 days of cumulative in vivo experience. This is seen as an important step toward a completely implantable ventricular assist system and total artificial heart. The TETS converts an external 12 volt DC source via inductive coupling to a regulated 14 volt output voltage for use by the motor controller. A maximum output power of 70 watts is available. In calf experiments, the TETS output power averaged between 8 and 12 watts. The motor controller was not implanted in these experiments, awaiting further development of the miniaturized electronics. The TETS output was returned percutaneously to the external motor controller, allowing the TETS output to be monitored directly. System efficiency, from DC source to DC output, and including losses in 12 feet of cable, ranged from 55% to To%, depending upon supply voltage, motor load, and degree of coil coupling. The subcutaneous coil was well tolerated, demonstrating only temporary, mild, superficial induration.
