Abstract

This paper discusses an implantable, low power, wireless, neural signal transmitter, to restore limb mobility in individuals with spinal cord injuries, as part of a Brain Computer Interface (BCI) system. Specifically, this paper describes a Brain Computer Interface (BCI) system using passive Radio Frequency Identification (RFID) transmitters operating in the Ultra High Frequency (UHF) band. This system uses backscatter modulation as its power transfer mechanism. Such low power UHF passive RFID radio technology has shown to have great potential to support invasive BCI applications. The performance of UHF passive RFID technology using a novel MAC protocol in an invasive BCI application is presented. The performance is analyzed using the novel MAC protocol and the following properties namely signal to noise ratio (SNR), received signal strength (RSS) and collision count were calculated and compared with the slotted Aloha protocol as a function of implant depth.

基于UHF- RFID无源后向散射调制的脑机接口(BCI) MAC协议实验研究

本文讨论了一种可植入的低功耗无线神经信号发射器，作为脑机接口(BCI)系统的一部分，用于恢复脊髓损伤患者的肢体活动能力。具体来说，本文描述了一个使用无源射频识别(RFID)发射机在超高频(UHF)频段工作的脑机接口(BCI)系统。该系统采用后向散射调制作为功率传输机制。这种低功率超高频无源RFID无线电技术已经显示出支持侵入性脑机接口应用的巨大潜力。介绍了一种新型MAC协议的超高频无源RFID技术在侵入式脑机接口应用中的性能。分析了新MAC协议的性能，计算了信噪比(SNR)、接收信号强度(RSS)和碰撞次数等特性，并与开槽Aloha协议作为植入深度的函数进行了比较。
