Enzymatic biofuel cells (EBFCs) are bioelectronic devices that utilize enzymes as the electrocatalysts to catalyze the oxidation of fuel and/or the reduction of oxygen or peroxide for energy conversion to electricity. Researchers in Ireland placed the electrodes between two commercially available contact lenses to avoid direct contact with the eye and tested them in a solution of artificial tears as well as one containing phosphate buffer solution. Hydrophilic silicon-hydrogel contact lenses contain microchannels that enable the transport of solutions and oxygen to the EBFC. This flexible EBFC holds potential as an autonomous power supply for wearable electronic devices… read more. TECHNICAL ARTICLE
