This diagram illustrates the principle behind the proposed energy-harvesting system. Two metal electrodes made of lithium-alloyed silicon form a sandwich around a layer of electrolyte, a polymer that ions (charged atoms) can move across. When the sandwich is bent, unequal stresses cause lithium ions to migrate across the electrolyte, producing a compensating electron current that can be harnessed ...
