Before revision:  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.
