Flexible polymer opals

A synthetic material which mimics the brightest and most vivid colours in nature, and changes colour when twisted or stretched, has been developed by researchers at the University of Cambridge, and could have important ...

Engineers monitor heart with paper-thin flexible 'skin'

(Phys.org) —Engineers combine layers of flexible materials into pressure sensors to create a wearable heart monitor thinner than a dollar bill. The skin-like device could one day provide doctors with a safer way to check ...

Harvesting unused energy with flat thermoelectrics

A large proportion of the energy we produce disappears unused into thin air via waste heat. Tiny thermoelectric generators can tap this potential, whereby the electricity is produced by way of temperature differences. However, ...

New solar-cell design based on dots and wires

Using exotic particles called quantum dots as the basis for a photovoltaic cell is not a new idea, but attempts to make such devices have not yet achieved sufficiently high efficiency in converting sunlight to power. A new ...

Whale's streaming baleen tangles to trap food

Many whales filter food from water using racks of baleen plates in their mouths, but no one had ever investigated how baleen behaves in real life. According to Alexander Werth from Hampden-Sydney College, baleen was viewed ...
