This new device may give humans ‘cat-like hearing’ Scientists are developing an atomically thin device that could receive and transmit signals across a radio frequency range far greater than what humans can hear. The “drumhead” device being developed by researchers at Case Western Reserve University in the US is trillion times smaller in volume and 100,000 times thinner than the human eardrum. The advance may lead to … Continue reading This new device may give humans ‘cat-like hearing’

New carbon fibre artificial muscles can lift 12,600 times their weight Scientists have designed new carbon fibre-based artificial muscles capable of lifting up to 12,600 times their own weight. The strong muscles are made from carbon fibre-reinforced siloxane rubber and have a coiled geometry. When electrically actuated, the artificial muscles show excellent performance without requiring a high input voltage, according to the study published in … Continue reading New carbon fibre artificial muscles can lift 12,600 times their weight

Solar cells that work in low light could charge devices indoors By Robert F. Service Apr. 23, 2018   Imagine never having to charge your phone, e-reader, or tablet again. Researchers report that they have created solar cells that work at a record efficiency for making electricity from the low-intensity diffuse light that is present inside buildings and outside on cloudy days. The solar cells could one … Continue reading Solar cells that work in low light could charge devices indoors

The technology that gave Stephen Hawking a voice   Stephen Hawking was one of the most prominent people in history to use a high-tech communication aid known as augmentative and alternative communication (AAC).   His death comes in the year of the 70th Anniversary of the Declaration of Human Rights. Over the course of his adult life, Hawking came to represent the epitome of what effective communication with … Continue reading The technology that gave Stephen Hawking a voice
