 Stimulation parameters are time-encoded on the fly through the wireless link rather than being programmed and stored on the mote, enabling complex stimulation protocols with precise timing and closed-loop capability and without the need for on-chip memory and power consumption . Uplink data indicates whether or not the mote is currently stimulating and is encoded by the mote via backscatter modulation and  demodulated at the external receiver. We characterize system power, stimulation performance, and acoustic link robustness under misalignment.

Uplink data indicates whether or not the mote is currently stimulating and is encoded by the mote via backscatter modulation and demodulated at the external transceiver. We show that the system operates at an acoustic power one fifth the FDA limit for diagnostic ultrasound and is robust to expected real-world acoustic link misalignment.
