1. A power providing device, comprising:
a first energy harvester element, of a plurality of energy harvester elements, configured as a transducer to generate power in response to an external ultrasonic signal being received;
a connection switching element, of a plurality of connection switching elements, configured to switch, dependent on a rectifying operation of a first rectifier, from a current configuration of the first energy harvester element being connected to a second energy harvester element, of a plurality of energy harvester elements, to a different configuration of the first energy harvester element and the second energy harvester element; and
the 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.
