Patent ID: 8830037

Claim:
An in vivo RFID chip implanted in a patient's body, comprising: a silicon substrate, a CMOS-compatible circuitry, and an integrated antenna integrally formed on the silicon substrate with the CMOS-compatible circuitry as a unitary chip structure, wherein neither the length nor the width of the silicon substrate with integrated antenna and CMOS-compatible circuitry exceeds 100 um, wherein the CMOS-compatible circuitry is adapted for biosensing and transmitting information out of the patient's body; wherein the CMOS-compatible circuitry is adapted to sense a chemical and/or physical quantity from a local environment in the patient's body and to control drug release from drug reservoirs based on the quantity sensed; and wherein the integrated antenna comprises a plurality of nanostructure based antennas, the nanostructure-based antennas formed from carbon single walled nanotubes (SWNTs).
