Abstract :
Among different energy sources, environmental mechanical vibrations represent one of the most ubiquitously available sources that can, potentially, deliver a useful amount of energy. In this paper a batteryless wireless node powered by a nonlinear bistable energy harvester is presented. The node is able to scavenge energy from wideband vibrations to transmit data by the SimpliciTI® network protocol @ 2.4 GHz. Several measurements have been performed in order to characterize the performances of the autonomous wireless node by observing the time t´ for the first transmission and the time interval, Δt, between consecutive transmissions in case of repeated cycles of mechanical stimulation. Results obtained encourage the use of the proposed nonlinear harvester to power wireless sensor nodes.
