HYBRID NANOGENERATOR FOR HARVESTING CHEMICAL AND MECHANICAL ENERGY

摘要

A fiber pressure sensor includes a carbon fiber. A generating unit includes a first insulator layer disposed about the carbon fiber adjacent a first end, a cathode disposed about a portion of the first insulator unit. The cathode includes a first conductor coupled to a glucose catalyzing enzyme, a second insulator layer disposed about the carbon fiber, and an anode disposed about a portion of the second insulator unit, the anode including a second conductor to which is coupled a an oxidase enzyme. A third electrode is disposed adjacent to the second end carbon fiber. A dense plurality of piezoelectric nanowires extends radially outwardly from the carbon fiber. A fourth electrode is in electrical communication with distal ends of the piezoelectric nanowires and is electrically coupled to the anode. A current sensor senses a current indicative of pressure applied to the dense plurality of piezoelectric nanowires.
