Neurophysiological wireless bio-sensor
First Claim
1. A wireless bipolar bio-sensor for attaching to the body of a subject for recording a biopotential signal, the bio-sensor comprising:
- a) a pair of electrodes capable of recording a biopotential signal from a subject;
b) a differential amplifier in contact with the electrodes and capable of generating an amplified differential signal from the signal recorded between the electrodes;
c) a miniaturized system-on-a-chip (SOC) attachment in contact with the differential amplifier, configured to process the signal received from the amplifier; and
d) an infra red light transmitter/receiver connected to the SOC attachment and capable of receiving optical power from a remote ir-light source transceiver, and of transmitting the signal thereto.

Abstract
This invention is directed to a wireless bio-sensor electrode for recording bio-potentials elicited from a subject or for providing a stimulus to a subject. A preferred embodiment is a wireless bio-sensor electrode for eliciting from a subject bio-potentials including averaged evoked potentials, nerve conduction studies, electromyographic activity, electrocardiogram or electroencephalogram, or for providing a stimulus to the subject for eliciting said bio-potentials. Another embodiment is the use of the wireless bio-sensor electrode for recording far-field and near-field bio-potentials in a subject in real-time and in a real-time neurophysiological monitoring/testing system.
