Flexible white LEDs made from existing tech

A highly-flexible yellow-tinged white-light LED created at National Chiao Tung University in Taiwan combines off-the-shelf parts with novel design patterns. The LEDs produce a uniform sheet of light and could soon find use in curved and flexible TVs and wearable displays.Read More

Flashing LEDs facilitate brain-controlled exoskeleton

Lower limb exoskeletons show great promise in helping those who have lost the use of their legs to walk again. However, if a person has been rendered quadriplegic, any hand controls in such a device are essentially useless. To help address this and other whole-of-body disabilities, scientists working at Korea University (KU) and Technische Universität Berlin (TU Berlin), have created a hands-free brain-to-computer interface to control a lower limb exoskeleton by specifically decoding signals from the wearer’s brain.Read More

Researchers create soft, weavable LED fibers for truly flexible wearable displays

Electronic displays for integration with clothing and textiles are a rapidly developing field in the realm of wearable electronics. However, flexible LEDs designed to form part of an elastic or deformable coating for clothing or apparel – even displays specifically designed to be directly bio-compatible – still rely on a hard substrate on which to layer the appropriate electroluminescent material. Now researchers at the Korea Advanced Institute of Science and Technology (KAIST) have created a fiber-like LED that can be directly knitted or woven to form part of the fabric itself.Read More

Ford's smart lighting technology spots potential hazards

There are some incredible technological strides being made to improve road safety, but the key to avoiding accidents remains the same: seeing what's ahead. Unfortunately, avoiding potentially dangerous situations before they pose a threat can be difficult on well sighted roads during the day, let alone at unlit junctions after the sun sets. To try and give drivers a better chance of avoiding hazards, Ford is developing headlight technology that widens the beam at junctions and detects pedestrians and animals.Read More

Review: We flip the switch on MiPow's Playbulb Bluetooth LED bulbs

The number of LED bulbs on the market has exploded in recent years, and with them has come a dizzying array of so-called smart bulbs featuring wireless connectivity and control, allowing users to set options for colors, schedules, and remote on/off functions. Although most of these look and perform similarly, consumer experience still varies as it generally comes down to the execution of the companion app. So how do the devices in MiPow’s Playbulb Studio compare? We lit up these LED bulbs to see how well they shine.Read More

Telecommunications

LED lightbulbs create wireless networks wherever they are installed

Various researchers have created ways to transmit wireless information from LED light fittings, to act as a form of enhancement to Wi-Fi based networks known as "Li-Fi." But now engineers at the University of Virginia (U.Va) have come up with a new twist on this theme – they claim to have created an algorithm that makes almost any device fitted with standard visible- light LEDs able to communicate with other equipment with similar LEDs. So, for example, the LED headlights in your car could communicate to the car in front of you through its LED taillights, or the LED display in your clock radio could tell the coffee maker to turn on via its indicator light.Read More
