Nanoengineers have developed a 'wearable microgrid' that harvests and stores energy from the human body to power small electronics. It consists of three main parts: sweat-powered biofuel cells, motion-powered devices called triboelectric generators, and energy-storing supercapacitors. All parts are flexible, washable and can be screen printed onto clothing.

Scientists have designed minimalist biostructures that imitate natural enzymes, capable of carrying out two differentiated and reversibly regulated activities thanks to a unique combination of structural and functional properties. The strategy used opens the door to the creation of 'intelligent' nanomaterials with tailor-made combinations of catalytic functions.

Researchers have realized an AI optical circuit, with a neural density equal to 1/400 of human brain. The circuit is trained to process information through unpowered all-optical inference at the speed of light with a computational power more than ten orders of magnitude larger than electronic processors. In future, its neural density is expected to be 10 times that of human brain.

Researchers have discovered a new two-dimensional material with unprecedented properties: regardless if it is strained or compressed, it always expands. This so-called half-auxetic behavior has not been observed before and is therefore very promising for the design of new applications, especially in nano-sensorics.
