Americans waste up to $19 billion annually in electricity costs due to “vampire appliances,” always-on digital devices in the home that suck power even when they are turned off. But now engineers have come up with a way to produce microscopic electronic switches for appliances and devices that can grow and dissolve wires inside the circuitry that instantly connect and disconnect electrical flow. With this technology, consumer products such as smartphones and computer laptops could run at least twice as long on a single battery charge, and newer all-digital appliances such as televisions and video game consoles could be much more power efficient.
