Abstract

The development of materials capable of harmlessly being broken down and removed from the body is a crucial step towards the development of short-term application electronic biomedical implants. Once developed, these implants, known as bioresorbable electronics, will open a wide array of temporary applications in the field of biomedical implantable devices. Necessary to the operation of bioresorbable electronics within the body is a power source that is similarly biocompatible and biodegradable. To this end, enhanced carbon-based materials and a bio-ionic liquid were developed for the fabrication of a preliminary implantable and bioresorbable battery and tested for functional properties. Electrodes were fabricated from carbonized fibers electrospun from solutions of PEO, Kraft Lignin, and a metal salt. The electrolyte was fabricated from fibers electrospun from solutions of PEO, GelMA, and Choline Acrylate. A complete battery set-up with both the fabricated anode, cathode, and electrolyte was characterized using Chronopotentiometry to obtain a potential value of 1.3 volts at an applied current density 0.71 µA /cm2.
