Abstract: Many countries have recently become interested in the deployment of cyber-physical systems (CPS) in industry and society for sustainable development. A CPS comprises a data acquisition function, a data storage function, and a network to transfer data. The move to deploy CPS in society makes it necessary to increase their energy efficiency and to find new energy sources. To overcome these energy-related issues, in this research we investigated the possibility of integrating data acquisition sensors with a recently developed energy harvesting system that combines the magnetic phase transition resulting from changes in temperature, and electromagnetic induction resulting from changes in magnetic flux. The proposed system can provide wireless temperature or velocity sensors that directly measure electromotive forces generated by a solenoid following Faraday's law without any additional energy input. Our proposed energy harvesting sensors have the potential to contribute significantly to the development of CPS in the near future.
