“…In addition, such polymer‐electrolyte glucose fuel cells exhibit low steady‐state power densities below 10 µW cm −2 . [ 24,78–82 ] In contrast, the ceramic glucose fuel cells reported here achieve competitive power densities, with that of the top‐performing device reaching 43 µW cm −2 , and the average power density across 12 glucose fuel cells reaching 11.4 µW cm −2 . In addition, the thickness of the ceramic glucose fuel cell is three times thinner than the next‐thinnest device, and ≈1000 times thinner than other abiotic glucose fuel cells reported to date.…”

Next‐generation implantable devices such as sensors, drug‐delivery systems, and electroceuticals require efficient, reliable, and highly miniaturized power sources. Existing power sources such as the Li–I2 pacemaker battery exhibit limited scale‐down potential without sacrificing capacity, and therefore, alternatives are needed to power miniaturized implants. This work shows that ceramic electrolytes can be used in potentially implantable glucose fuel cells with unprecedented miniaturization. Specifically, a ceramic glucose fuel cell—based on the proton‐conducting electrolyte ceria—that is composed of a freestanding membrane of thickness below 400 nm and fully integrated into silicon for easy integration into bioelectronics is demonstrated. In contrast to polymeric membranes, all materials used are highly temperature stable, making thermal sterilization for implantation trivial. A peak power density of 43 µW cm−2, and an unusually high statistical verification of successful fabrication and electrochemical function across 150 devices for open‐circuit voltage and 12 devices for power density, enabled by a specifically designed testing apparatus and protocol, is demonstrated. The findings demonstrate that ceramic‐based micro‐glucose‐fuel‐cells constitute the smallest potentially implantable power sources to date and are viable options to power the next generation of highly miniaturized implantable medical devices.
