It could be a crystal ball from a mythical age showing the swirling mists of time, but James Macleod’s image, which has won this year’s Department of Engineering Photography Competition, actually shows graphene being processed in alcohol to produce conductive ink.
A new method for producing conductive cotton fabrics using graphene-based inks opens up new possibilities for flexible and wearable electronics, without the use of expensive and toxic processing steps.
Researchers have discovered a way to remove specific fears from the brain, using a combination of artificial intelligence and brain scanning technology. Their technique, published in the inaugural edition of Nature Human Behaviour, could lead to a new way of treating patients with conditions such as post-traumatic stress disorder (PTSD) and phobias.
Healthcare is a complex beast and too often problems arise that can put patients’ health – and in some cases, lives – at risk. A collaboration between the Cambridge Centre for Health Services Research and the Department of Engineering hopes to get to the bottom of what’s going wrong – and to offer new ways of solving the problems.
Cambridge researchers and students have recreated John Logie Baird’s cumbersome ‘flying spot’ camera for a documentary about the first live scheduled BBC television broadcast on 2 November 1936.
Researchers have identified the cause of chronic, and currently untreatable, pain in those with amputations and severe nerve damage, as well as a potential treatment which relies on engineering instead of drugs.
A new design for transistors which operate on ‘scavenged’ energy from their environment could form the basis for devices which function for months or years without a battery, and could be used for wearable or implantable electronics.
Computers that learn for themselves are with us now. As they become more common in ‘high-stakes’ applications like robotic surgery, terrorism detection and driverless cars, researchers ask what can be done to make sure we can trust them.
