We’re probably all familiar with the Hall Effect, at least to the extent that it can be used to make solid-state sensors for magnetic fields. It’s a cool bit of applied physics, but there are other ...

The versatile design framework is not limited to sensors that harvest magnetic field energy, and can be applied to those that use other power sources, like vibrations or sunlight. It could be used to ...

A fluid that retains its magnetic structure when an external magnetic field is removed can form the basis of liquid bioelectronics 1. A ferrofluid is a substance consisting of nanometre-sized magnetic ...
