WIRELESS HIGH-DENSITY MICRO-ELECTROCORTICOGRAPHIC DEVICE |
摘要 |
A minimally invasive, wireless ECoG microsystem is provided for chronic and stable neural recording. Wireless powering and readout are combined with a dual rectification power management circuitry to simultaneously power to and transmit a continuous stream of data from an implant with a micro ECoG array and an external reader. Area and power reduction techniques in the baseband and wireless subsystem result in over 10×IC area reduction with a simultaneous 3× improvement in power efficiency, enabling a minimally invasive platform for 64-channel recording. The low power consumption of the IC, together with the antenna integration strategy, enables remote powering at 3× below established safety limits, while the small size and flexibility of the implant minimizes the foreign body response. |
