A $24\,\mu \text{W}$ , Batteryless, Crystal-free, Multinode Synchronized SoC “Bionode” for Wireless Prosthesis Control

We present a batteryless, crystal-free, time division multiple access (TDMA) synchronized multinode wireless body sensor node (WBSN) system-on-chip (SoC), referred to as a Bionode, for continuous and real-time telemetry of electromyograms (EMGs), enabling intuitive upper limb prosthesis control by an amputee. The SoC utilizes state of the art in supercapacitive RF energy harvesting, biosensing ana...
