Fabrication of Needle-type Solid-state CMOS-compatible Glucose Fuel Cell Using Carbon Nanotube for Biomedical Application

Abstract

A solid-state CMOS-compatible glucose fuel cell was fabricated in an anode area using 1D structural carbon nanotubes (CNTs), which exhibits an open-circuit voltage (OCV) of 330 mV and a power density of 7.5 µW/cm 2 at a glucose concentration of 30 mM. The developed fuel cell was manufactured using a semiconductor (CMOS) fabrication process from materials biocompatible with the human body. The CNTs improved the fuel cell performance owing to their high electrocatalytic capability. We have introduced CNTs to the fabrication of a needletype CMOS-compatible glucose fuel cell. In this paper, we present a (17.5 × 0.7 mm 2) solidstate CMOS-compatible glucose fuel cell with an OCV of 330 mV at a glucose concentration of 30 mM, which is the highest OCV for a glucose fuel cell when the anode area is 4.86 mm 2 (16.2 × 0.3 mm 2). The highest power is 0.36 µW. Power generation is the main challenge in the fabrication of glucose fuel cells for biomedical applications.
