Outline of Final Research Achievements

The possibility of integrating data acquisition sensors with a recently developed energy harvesting system that combines the magnetic phase transition and electromagnetic induction was investigated in this research.
Magnetothermal properties such as magnetic flux change throughout a magnetic phase transition were experimentally measured to examine characteristics that have strong implications for the proposed temperature sensor. The potential of changing the magnetic moment in a temperature sensor was evaluated. In addition, an appropriate magnetic material was searched and implemented to the proposed sensors.
These investigations demonstrate that the proposed system has great potential for application as an energy harvesting sensor.
