As engineers attempt to integrate electronics into things like clothing and medical devices, they're increasingly running up against the material properties of the substances we use to make the hardware. A lot of the materials that go into a typical electronic device are brittle, inflexible, and prone to damage, and materials scientists are looking at a variety of options for replacing them. A recent paper in Advanced Functional Materials describes a technique for forming an antenna from liquid metal. The resulting (not-so-) hardware is flexible, self-healing, and can change the frequency that it's sensitive to based on the stress it's subjected to.
