Abstract:
1. A bio-sensor system powered by an electro-active polymer (EAP) generator and being adapted to provide a substantially stable voltage to a sensor assembly that is implantable in a patient such that physiological Parameters thereof may be accurately measured, the bio-sensor system comprising: a remote transponder configured to transmit a scanner signal to an implantable on-chip transponder and to receive a data signal therefrom; the implantable on-chip transponder in wireless communication with the remote transponder and being configured to receive the scanner signal and transmit the data signal, the on-chip transponder including: wherein the power supply is configured to supply a substantially non-deviating sensor reference voltage to the sensor for accurate measurement of the physiological parameter, the remote transponder being configured to receive the data signal from the RF transmitter and to extract data representative of the physiological parameter; wherein the sensor is a glucose sensor having an electrode assembly adapted to be in fluid communication with the patient's blood and being configured to measure a glucose level thereof; wherein the sensor reference voltage is supplied to the electrode assembly at a substantially constant value of about positive 0.7 volts; wherein the glucose sensor is a 2-pin glucose sensor with the electrode assembly having first and second terminals adapted to be in fluid communication with the patient's blood, the glucose sensor further including:
