This study proposes a double elastic steel sheet vibration energy harvester system (DESS VEH), where the vibration generated by the deformation and/or clap of two magnetic excited elastic steel sheets is assisted by a piezo-patch to generate electric energy. The proposed model can be applied on an unmanned helicopterany other multi-rotor drones. The downstream flows from the rotors are collecteddriving a wind-turbine to excite the vibration steel sheet(s) systemgenerating electric power.

This technology aims to develop a set of UAV observationmonitoring technology for the atmospheric boundary layer. The Key technologies include mission-oriented integration technology, ultra-high vertical flight capability, long-distance data wireless transmission, real-time data displaycorrection, automatic take-off, data analysis technology,data upload to the cloud in 4G. This technology has participated in international experimentshas entered the stage of international promotion.
