Abstract

This chapter describes a fully integrated neural interface which wirelessly streams a digitized neural waveform over 15m [2]. In contrast to the NeuralWISP described in the previous chapter, this system is designed to operate from a small battery. The battery allows the system to operate at a greater range from the receiver and to transmit more data. Because of the low power consumption in the analog front end and the wireless transmitter, the system can operate from a very small battery, resulting in an extremely lightweight system with a small form-factor.
