Wiegand Energieoogst

What is Wiegand effect energy harvesting?

The Wiegand efect is another energy harvesting technology that generates electrical energy from mechanical motion, in this case, rotations or oscillating motions. Wiegand efect energy harvesting is reliable and eficient, capable of producing consistent levels of energy, even when the underlying motions occur very slowly.

What is Wiegand technology?

Wiegand technology has a strong track record, with proven successes in niche applications such as fluid metering and rotary encoders. It also has significant potential for more advanced uses, both as a sensor for detecting mechanical motions and as an energy harvesting device for self-contained electronic devices.

Are Wiegand sensors a good candidate for energy harvesting?

Wiegand sensors are also a good candidate for energy harvesting. In their basic form, these devices produce modest amounts of energy—about 200 nanojoules. However, recent developments have significantly increased energy output from Wiegand devices and opened possibilities for much more ambitious applications.

What is a Wiegand sensor?

The combination of a short length of Wiegand wire and a surrounding copper coil is referred to as a Wiegand sensor. These are available commercially from UBITO in surface mountable device (SMD) packaging. “Energy harvesting” refers to technologies that extract energy from the local environment to power electronic devices.

What is the Wiegand effect?

The Wiegand effect is a physical phenomenon discovered in the 1970s by John Wiegand, an American inventor who found that by repeatedly stretching and twisting a piece of ferromagnetic wire, he could alter its magnetic properties.

Is Wiegand technology the future of the Internet of things?

With enhancements to the energy output from Wiegand devices and the emergence of a new generation of ultra-efficient electronic chips, the technology is showing significant promise, especially in the exciting area of the Industrial Internet of Things (IIoT).
