A low power wireless sensor node with vibration sensing and energy harvesting capability

This paper describes the design of the wireless sensor network node (WSN) for distributed active vibration control (AVC) system for the automotive application. The approach of the system is presented in details. A WSN node using one piezoelectric element provides several features (sensing, shunting and energy harvesting). Integration of the vibration sensing capability for active vibration control system with the energy harvesting capability is described here. Simulation results are compared with the prototype design.
