A small, light-weight, low-power, multichannel wireless neural recording microsystem.
A small (<1cm(3)), light-weight (<1g including batteries), low power (10mW, lasts 25 hrs), long range (22 ft.), 3-channel wireless neural recording system is designed, fabricated and characterized through in-vitro and in-vivo experiments. The transmitter comprises of an ASIC fabricated in 2-Poly, 2-Metal 1.5 microm AMIS process which can transmit data out wirelessly using on-chip VCO or low power commercial off-the-shelf (COTS) transmitters. The microsystem is employed in collecting neural signals from two different animal models: axons in cockroach leg and forelimb area of the motor cortex of a mature Long Evans rat.
