Abstract: A method of harvesting energy that includes providing an insert for a shoe, receiving a mechanical signal by one or more of at least two electromechanical transducers disposed along opposite surfaces of the insert, and converting the mechanical signal into an electrical signal. The method further includes converting the electrical signal from an alternating current to a direct current and discharging the direct current into a power bank when a bridge circuit of the insert is electrically coupled to the power bank.
