Technical line drawing cutaway of a shoe showing piezoelectric sensors, generator, and battery with labels pointing to each component.

A clean technical line drawing of a piezoelectric shoe with a built-in generator and battery. Side view of a shoe cutaway showing a foot pressing down on an insole with two piezoelectric disc sensors at the heel and ball of the foot. Wires run from the sensors to a small generator module attached to the side of the shoe. The generator connects to a rechargeable battery pack at the ankle. A small LED and USB port are also shown. White background, black lines, engineering schematic style, labels pointing to each component including piezo sensors, generator, battery, rectifier, and output. See more
