This energy management interface is the "brain" of a self-powered, battery-free sensor that can harvest the energy it needs to operate from the magnetic field generated in the open air around a wire.

What the magnetoelastic effect is and how it can be used. How an innovative design and fabrication technique led to a flexible magnetoelastic device. How this unique device can be used for both energy ...

The sensor framework described in a recent journal by MIT scientists can also use other sources of energy such as vibrations or sunlight. Scientists have created a new type of sensor that does not ...

Measuring a magnetic field can be very easy with some pretty low tech, or it can be very high tech. It just depends on what kind of measurement you need and how much effort you want to expend. The ...

Most of the hacks we see around these parts have to do with taking existing components and cobbling them together in interesting new ways. It’s less often that we see existing components gutted and ...
