经皮能量传输系统（TETS）由一对线圈、驱动电路和整流电路组成，线圈穿过皮肤形成一个Transformer。通过使用无芯线圈和高驱动频率（100-160 kHz），可以以78.5%的最大效率（直流到直流）传输超过25 W的电力。在动物实验中，在热谱图上，操作期间的初级线圈温度低于39°C。在植入环氧树脂涂层的次级弹簧圈10个月后，它被连接组织的薄囊包裹。未发现明显的组织反应。
A transcutaneous energy transmission system (TETS) was composed of a couple of coils, which formed a transformer across the skin, a driving circuit, and a rectifying circuit. By using coreless coils and a high driving frequency (100–160 kHz), more than 25 W of electric power could be transmitted with 78.5% of maximum efficiency (dc to dc). In animal experiments, the primary coil temperature during operation was under 39°C on thermograms. After 10 months of implantation of a secondary coil coated with epoxy resin, it was wrapped by a thin capsule of connecting tissue. No obvious tissue reaction was recognized.
