A 0.43 g Wireless Battery-Less Neural Recorder With On-Chip Microelectrode Array and Integrated Flexible Antenna

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.

Description
Summary: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 vivo measurements on an unrestricted mouse have been successfully conducted, showing response to visual stimuli.
