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 700 mV, 30 to 40 uA load attained at -2 dBm.
开发完全可植入的无线供电神经接口存在重大技术挑战。这些挑战包括向植入设备无线传输足够的电力，以确保其在无需更换的情况下可靠运行数十年；将组织发热降至最低；以及具备足够可靠的通信带宽。克服这些挑战对于开发用于治疗癫痫、尿失禁、中风和脊髓损伤等疾病的植入式闭环系统至关重要。我们讨论了一种射频识别传感器（RFIDS）系统的无线供电、通信和控制的开发情况，该系统针对在-2 dBm时为700 mV、30至40 μA负载实现的目标功率范围。
