Answer 1

EM-VEH ia an attractive alternative to batteries as apower source for wireless sensor nodes that enable intelligence at the edge of the IOT. Industrial enviroments in particular enviroments in particular offer an abundance of available kinetic enenrgy harvesting techniques. These vibrations are generally broadband and multi-modal harvesting confriguations can be exploited to improve the mechanical to electrical energy conversion. The results show that the device and the power management circuit provide sufficient energy to recieve and transmit data at intervals of less than one minute with an overall efficiency of about 30%. Description of the system,test bench and the measured outcomes are presented
