Short summary
The paper describes a novel energy-harvesting system based on the Wiegand effect. The energy provided by this harvester is analysed and correlated to the required energy to start a microcontroller and perform some wireless data transfer. The energy consumption is analysed in detail down to component level. A demonstrator including an additional sensor and wireless transmitter was built, proving that sufficient energy is provided by the harvester for the wireless transfer of the sensor data.
