Graphene turns 15 on track to deliver on its promises
Scientists analyze the current graphene landscape and market forecast for graphene over the following decade.
Read morePrinted electronics open way for electrified tattoos and personalized biosensors
Electrical engineers have devised a fully print-in-place technique for printable electronics that is gentle enough to work on delicate surfaces ranging from paper to human skin. This can be accomplished without additional steps to bake, wash or powder-coat materials. The advance could enable technologies such as high-adhesion, embedded electronic tattoos and bandages with patient-specific biosensors.

Accurately measuring frequencies of light is required for timekeeping and many science experiments and technologies. Frequency combs, invented in 2000, are used to complete these measurements. However, most of them are large and cumbersome. In 2009, researchers developed a way to make much smaller combs, but they came with their own challenges. New research finds that a novel way of generating frequency combs could address these challenges, leading to compact frequency combs with untold applications.

Scientists have helped three amputees merge with their bionic prosthetic legs as they climb over various obstacles without having to look. The amputees report using and feeling their bionic leg as part of their own body, thanks to sensory feedback from the prosthetic leg that is delivered to nerves in the leg's stump.
Object identification and interaction with a smartphone knock
Scientists have developed new technology, dubbed 'Knocker', which identifies objects and executes actions just by knocking on them with the smartphone. Software powered by machine learning of sounds, vibrations, and other reactions will follow the users' directions.

Researchers have enabled, for the first time, determining whether the person behind a wall is the same individual who appears in given video footage, using only a pair of WiFi transceivers outside.
Read moreCurved nanochannels allow independent tuning of charge and spin currents
To increase the efficiency of microchips, 3D structures are now being investigated. However, spintronic components, which rely on electron spin rather than charge, are always flat. To investigate how to connect these to 3D electronics, physicists have created curved spin transport channels. They discovered that this new geometry makes it possible to independently tune charge and spin currents.
