Abstract

The self-powered device is configured to be powered by energy collected from a surrounding environment. The self-powered device includes an energy collector, and a memory having instructions for selecting one of a plurality of modes of operation. The energy collector is configured to collect energy to power the self-powered device from a surrounding environment in which the self-powered device is located. The plurality of modes of operation include: (i) a low-power mode of operation in which the self-powered device consumes less than a pre-determined or adaptively-determined amount of power and the self-powered device uses less than its full capabilities, and (ii) and a high-power mode of operation in which self-powered device consumes more than the pre-determined or adaptively-determined amount of power and the self-powered device uses its full capabilities. The instructions for selecting one of a plurality of modes of are configured to (a) select the low-power mode of operation when available energy becomes insufficient to fully power the self-powered device, and (b) select the high-power mode of operation when sufficient energy again becomes available to fully power the self-powered device.
