Abstract:
1. A method of remotely monitoring physiological parameters using a bio-sensor system comprising a remote transponder and an on-chip transponder having a sensor implantable in a patient, the method comprising the steps of: a. remotely generating and wirelessly transmitting a scanner signal with the remote transponder, the scanner signal containing radio signal power and a telemetry data request; b. receiving the scanner signal at the on-chip transponder and filtering, amplifying and demodulating the scanner signal to generate a message signal in response thereto; c. collecting the radio signal power from the scanner signal and generating a power signal in response thereto; d. sensing at least one physiological parameter of the patient at the sensor and generating an analog sensor signal in response thereto; e. receiving the power signal, the analog sensor signal and the message signal at an analog-to-digital (A/D) assembly and generating a digital signal representative of the analog sensor signal; f. receiving the power signal, the message signal and the digital signal at a data processor and preparing the digital signal for modulation and generating a data signal representative of the digital signal; g. receiving the power signal, the message signal and the data signal at a radio frequency (RF) transmitter and modulating, amplifying, filtering and wirelessly transmitting the data signal; and h. receiving the data signal at the remote transponder and extracting data representative of the physiological parameter of the patient;  wherein the sensor is a 2-pin glucose sensor having an electrode assembly with first and second terminals adapted to be placed in fluid communication with the patient's blood for sensing a glucose level of the patient, step (d) further comprising the steps of:
