Glucose-activated laminated battery

The feasibility of fabricating glucose-activated paper battery based on glucose-oxidase enzyme using a simple and cheap plastic laminating technology is demonstrated. Through a simple lamination process, the battery is constructed by passing a stack consisted of the magnesium, enzyme-doped special paper, copper sandwiched between two plastic films into a roller which bound the whole assembly together. The single battery can deliver a stable voltage and power output of 0.8-1 V and 0.1-0.8 mW, respectively. We can also optimize the enzyme and glucose concentration as well as the prototype design to gear up the power requirement. This novel idea of making glucose-activated battery by plastic lamination technology could offer cheap alternative power for many potential energy-powered medical devices, such as an integrated disposable bio-systems providing onboard power source for the sensing unit and detection of the analytes of interest.
