Abstract

This paper presents the integration of the fabrication processes for an implantable multi-analyte biochip system. The implantable biochip system has a microfluidic channel in which an electrochemical biosensor and a dielectrophoresis (DEP) micropump are fabricated by surface micromachining. The enzyme-based biosensor consists of three electrodes and detects the glucose level instantaneously by utilizing glucose oxidase (GOD). The DEP force resulting from the four-phase voltage exchange of the interdigitated electrodes drives the blood flow in the microchannel. By utilizing the MEMS fabrication and the electric circuit design, a compact implantable biochip system is achieved.
