Synchronous Generation of Electrical and Cellular Energies via Body-Mediated Energy Transfer: Inevitable Electric Field Concentration

The effect of body-mediated energy transfer and harvestingon biologicaltissues has not been considered yet. We demonstrate through clinicalprotocols that body-mediated energy harvesting concentrates inevitableand local electric fields in biological tissues, which reduces musclefatigue (6.4%, P-value = 0.020). The waveform (ACand DC) and intensity (similar to 3000 mV/mm) of these electric fieldscan be adjusted by controlling several variables (grounding method,external resistance, charging capacitor) depending on the purpose(usefulness, energy strength) without using any additional batteryor wiring. Moreover, the harvested energy can be used to operate smallelectronic devices semipermanently. These findings indicate that body-mediatedenergy harvesting is a promising solution for powering wearable technologiesand as a noninvasive treatment for harvesting energy and stimulatingbiological tissues synchronously.
