无线电力输送和遥测是植入式设备的关键方面，该植入式设备能够长期运行，否则会受到电池容量（电池供电系统）、感染和疼痛（系留系统）等因素的限制。在本文中，我们提出了我们的高效的无线电力传输和可靠的遥测平台，使一个完全植入式肌肉刺激器。100 mW的整流功率以超过40%的效率输送到植入体，并支持2.4 Kbps的双向遥测，误码率小于10-7。该无线平台在大鼠中进行了长期测试。使用加热测量确保电气安全，并且它们预示着模拟结果良好。
Wireless power delivery and telemetry are the key aspects of an implantable device that enables long-term operation which is otherwise limited by the factors like battery capacity (in battery operated systems), infections and pain (tethered systems). In this paper, we present our efficient wireless power delivery and reliable telemetry platform that enables a completely implantable muscle stimulator. 100 mW of rectified power is delivered to the implant at an efficiency of over 40% and supports bidirectional telemetry at 2.4 Kbps with a bit error rate lesser than 10-7. The wireless platform is tested chronically in rats. Electrical safety is ensured using heating measurements and they augur well with simulation results.
