METHOD AND APPARATUS TO CREATE ELECTRIC POWER GENERATED FROM AN EXTERNAL ENERGY SIGNAL USING A PLURALITY OF ENERGY HARVESTING ELEMENTS

A power providing device is provided. The power providing device includes a first energy harvester element configured to generate power in response to an external energy signal being received, a connection switching element configured to switch a connection between the first energy harvester element and a second energy harvester element; and a first rectifier comprising one or more path switching elements configured to change a rectification path in response to the switching of the connection switching element, wherein the first rectifier is connected to the first energy harvester element to rectify the power generated by the first energy harvester element along the rectification path.
