摘要
A wireless sensor device includes: an energy harvester configured to convert vibration generated from a broadband vibration source into electricity, an elastic member arranged to receive the vibration and a communication unit fixed by the elastic member, supplied with the converted electricity from the energy harvester, and configured to transmit sensing information obtained by sensing a measurement target. The elastic member operates as a mechanical filter configured to limit a frequency range and an acceleration magnitude of the vibration to be transferred to the communication unit for stabilizing the performance of the communication unit, and the communication unit is arranged to receive vibration passing through the elastic member.
