Embodiments of the invention described herein use an output of an energy harvester (104) as an indication of the operating state of the machine (102), device, or process the energy harvester (104) is associated with. In one aspect, a system is described. The system is comprised of at least one of a machine (102) or process, a processor (108), and an energy harvesting device (104) associated with the machine (102) or process. The processor (108) is configured to use an output of the energy harvesting device (104) created by the machine (104) or process to determine whether the machine (102) or process is in a first operating state or a second operating state.
