Abstract
A system for harvesting energy from a lubrication event includes a fluid pump, a fluid injector, an energy harvesting device, a wireless transmitter, and a controller unit. The fluid injector receives fluid from the fluid pump. The fluid injector is connected to the energy harvesting device, which is configured to produce electrical energy in response to a firing of the fluid injector. Electrical energy produced by the energy harvesting device powers the wireless transmitter, which is configured to transmit a wireless signal. The wireless signal indicates that the fluid injector fired. The wireless signal is received by the controller unit, which controls the fluid pump.
