Researchers at the Georgia Institute of Technology have developed devices to generate electricity from pressure ripple at power levels that enable wireless sensing and communications, among other applications. In a hydraulic system, an energy harvesting technology might be integrated with health monitoring sensors and eliminate the need for batteries or wires providing power to individual sensors; this would reduce maintenance contact and eliminate potential points of failure.
Read this white paper to learn how hydraulic pressure can help you harvest energy for low power wireless devices.
