Description

A high-sensitivity, fully passive neurosensing system is presented for wireless brain signal monitoring. The proposed system is able to detect very low-power brain-like signals, viz. as low as -82 dBm

A high-sensitivity, fully passive neurosensing system is presented for wireless brain signal monitoring. The proposed system is able to detect very low-power brain-like signals, viz. as low as -82 dBm (50 μVpp) at fneuro > 1 kHz. It is also able to read emulated neural signals as low as -70 dBm (200 μVpp) at fneuro > 100 Hz. This is an improvement of up to 22 dB in sensitivity as compared with previously reported neural signals. The system is comprised of an implanted neurosensor and an exterior interrogator.
