在开发完全可植入的无线供电神经接口方面存在着重大的技术挑战。挑战包括向植入的设备无线传输足够的功率以确保数十年的可靠运行而无需更换，最大限度地减少组织加热，以及足够的可靠通信带宽。克服这些挑战对于开发用于治疗癫痫、大小便失禁、中风和脊髓损伤等疾病的植入式闭环系统至关重要。本文讨论了射频识别传感器(RFIDS)系统的无线功率、通信和控制的发展，目标功率范围为700 mV，30-40uA负载，−为2dBm。
There are significant technical challenges in the development of a fully implantable wirelessly powered neural interface. Challenges include wireless transmission of sufficient power to the implanted device to ensure reliable operation for decades without replacement, minimizing tissue heating, and adequate reliable communications bandwidth. Overcoming these challenges is essential for the development of implantable closed loop system for the treatment of disorders ranging from epilepsy, incontinence, stroke and spinal cord injury. We discuss the development of the wireless power, communication and control for a Radio-Frequency Identification Sensor (RFIDS) system with targeted power range for a 700mV, 30 to 40uA load attained at −2dBm.
