Abstract
An e-garment that includes embedded circuitry and a battery for power the embedded circuitry further includes several charge generator circuits that can include both active and passive charge generators, such as solar cells, triboelectric generator, piezoelectric generator, and thermoelectric generator circuits. Each different generator circuit accumulates charge in a respective storage capacitor until the voltage of the respective capacitor is sufficiently higher than that of the battery to overcome the forward voltage bias of a protective diode, where some of the charge flows out of the capacitor to the battery. Each of the charger generator circuits can contribute charge to the battery to prolong its operating time needed between recharges, if not actually recharge the battery.
