(337i) Energy Harvesting Wireless Sensors Using Magnetic Phase Transition

Most industries are connected by cyber-physical systems (CPS), and data and energy in manufacturing technologies are exchanged and shared or sustainable development. To deploy CPS, it is necessary to develop overall security systems, to increase their efficiency including data transfer systems in the network and acquisition systems, and to find new energy sources.

To overcome these energy-related issues of CPS, the possibility of integrating data acquisition sensors with energy harvesting system has been investigated to design energy harvesting sensors in this research. In this energy harvesting system, the magnetic phase transition resulting from changes in temperature is combined with electromagnetic induction, leading to conversion from heat to electricity in the system. In addition, we can successively measure the electromotive force as sensing targets. The proposed system can provide wireless temperature or velocity sensors that directly measure electromotive forces generated by Faraday's law of induction without any additional energy input. Our proposed energy harvesting sensors have the promising potential to contribute significantly to the development of CPS in the near future.
