Synopsis

Modern demand of portable electronics and computing have led to the development of batteries with high power densities. However, many of these options use highly toxic, volatile, and non-biodegradable chemicals. A battery was developed using common bacteria as its main generator of ions, with printed anode and cathodes on an specially-treated multi-layer paper membrane architecture. This developed battery offers potential for small, easily-manufactured power sources for disposable biomedical sensors, electronic chemical sensors, and environmental sensor applications.
