Supercapacitors Get Smaller Than Ever

Electrical, Electronics & Instrumentation

As smart devices, wearable sensors, IoT technologies, and implantable electronics shrink in size, so too should the energy-storage devices they rely on. Supercapacitors—with high capacity for energy storage but also a capability to handle rapid charge-discharge cycles that would founder a conventional chemical battery—have in recent years shrunk to “micro”…

Stretchy Devices Spin Electricity From Body Heat

Electrical, Electronics & Instrumentation

Phones, appliances, and humans all generate heat that usually escapes into the environment as waste energy. Thermoelectric generators, which convert temperature differences into electricity, are a way to capture that wasted heat for power.Researchers have now made a thermoelectric generator (TEG) that is soft and stretchy and that biodegrades completely…

Stacking Turns Organic Transistors Up

Electrical, Electronics & Instrumentation, Metallurgy & Material Science

Organic electronics appear to be, as the name might imply, quite good at interacting with a biological body and brain. Now scientists have created record-breaking, high-performance organic electronic devices using a potentially cheap, easy, and scalable approach that adopts a vertical architecture instead of a flat one, according to a…
