ETRI develops a haptic film activated by LEDs

LED-based film-type haptic technology implements localized vibration. Various tactile sensations are now possible via independantly controllable vibrations. A Korean research team succeeded in developing a technology generating various vibration using…

Designing selective membranes for batteries using a drug discovery toolbox

By binding specific ions in specially designed cages within its pores, a new membrane could enable more efficient flows in energy storage devices. Membranes that allow certain molecules to quickly…

Smart glass has a bright future

Light modulation via optical MEMS microshutter and micromirror arrays could provide huge energy savings. Buildings are responsible for 40 percent of primary energy consumption and 36 percent of total CO2…

Economical wireless communication

In today’s world, more and more devices are being wirelessly connected to one another with the aid of intelligent sensors. As this Internet of Things keeps growing, however, it is…

Tailor-made power grids

Empa researcher Cristina Dominguez is developing a computer model, which can be used to plan electricity grids in developing countries. To collect data, she travelled to Kenya to get an…

Even without a brain, metal-eating robots can search for food

When it comes to powering mobile robots, batteries present a problematic paradox: the more energy they contain, the more they weigh, and thus the more energy the robot needs to…

Scientists show technology can save people from shark bites

The deployment of personal electronic deterrents is an effective way to prevent future deaths and injuries. With shark bites increasing in countries like Australia – scientists say the use of…

An industrially viable competitor to silicon-based solar cells is in the works

Researchers from Kanazawa University fabricated a highly efficient perovskite solar cell with nearly the energy conversion efficiency of commercial silicon-based solar cells, which can be produced on a large scale….

Molecular Electronics: Trapped molecule in contact

There are worlds between the Zuse Z3, the first functioning digital computer from 1941, and modern microprocessors – both in terms of speed and size. But the further miniaturization of…

New nanotransistors keep their cool at high voltages

Power converters are the little-known systems that make electricity so magical. They are what allow us to plug in our computers, lamps and televisions and turn them on in a…
