Energy Harvesting with Wiegand

Wiegand Sensors

Harnessing Pulse Power

The pulse energy produced by POSITAL’s Wiegand sensors in response to changing external magnetic fields can be harnessed to power electronics. Successive pulses to be stored to offset energy demand of circuits and, in the case of modern ultra-low power ICs, a single pulse can provide sufficient energy for intermittent operation.

Applications: Mechanical Energy Harvesting

Mechanical energy can be converted into pulse energy through a number or implementations including; static magnet/moving wire, static wire/moving magnet, or even a moving ferromagnetic body distorting the magnetic field around the Wiegand wire.

Wireless Power Transmission

In combination with low-frequency electromagnetic fields, POSITAL Wiegand sensors can be used to provide energy for low power applications in environments where high frequency transmission is challenging (e.g. transcutaneous power for medical devices).

Self-sufficient IoT Sensors

With the emergence of ultra-efficient electronic chips and low power wireless communications technologies, there is potential for the integration of Wiegand Sensors into energy self-sufficient, maintenance-free IoT sensors.
