Enhancement in open-circuit voltage of implantable CMOS-compatible glucose fuel cell by improving the anodic catalyst

This paper presents an implantable CMOS-compatible glucose fuel cell that generates an open-circuit voltage (OCV) of 880 mV. The developed fuel cell is solid-catalyst-based and manufactured from biocompatible materials; thus, it can be implanted to the human body. Additionally, since the cell can be...

Description
Summary:This paper presents an implantable CMOS-compatible glucose fuel cell that generates an open-circuit voltage (OCV) of 880 mV. The developed fuel cell is solid-catalyst-based and manufactured from biocompatible materials; thus, it can be implanted to the human body. Additionally, since the cell can be manufactured using a semiconductor (CMOS) fabrication process, it can also be manufactured together with CMOS circuits on a single silicon wafer. In the literature, an implantable CMOS-compatible glucose fuel cell has been reported. However, its OCV is 192 mV, which is insufficient for CMOS circuit operation. In this work, we have enhanced the performance of the fuel cell by improving the electrocatalytic ability of the anode. The prototype with the newly proposed Pt/carbon nanotube (CNT) anode structure successfully achieved an OCV of 880 mV, which is the highest ever reported.
