Year: 2022

Type: article

Abstract: This work presents a single-chip battery-less neural recorder with 12 on-die microelectrodes. It can be powered wirelessly up to 16 cm away from a horn antenna at 915 MHz and only consumes 104$\mu \text{W}$dc power for accessing ten enabled recording sites simultaneously, transmitting at 5 Mb/s. The implantable device integrated with a flexible antenna weighs only 0.43 g.In vivomeasurements on an unrestricted mouse have been successfully conducted, showing response to visual stimuli.
