Graphene switches bring minute electronics a step closer

Graphene switches bring minute electronics a step closer
Researchers have discovered how to control molecules attached to graphene, paving the way for tiny biological sensors and devices to hold information. Graphene is a material made of a single sheet of carbon atoms in a honeycomb arrangement. Because of its unique electrical conductivity, graphene has the potential to be a base for electronic devices that are only nanometres (billionths of a metre) in size.

Sensor material enables sensitive readings of biological signals

Sensor material enables sensitive readings of biological signals
  Scientists have created a material that could make reading biological signals, from heartbeats to brainwaves, much more sensitive. Organic electrochemical transistors (OECTs) are designed to measure signals created by electrical impulses in the body, such as heartbeats or brainwaves. However, they are currently only able to measure certain signals.

'Bionic eye' monitors industrial assembly lines

'Bionic eye' monitors industrial assembly lines
Scientists are developing a 'bionic eye' that could be used by manufacturers to improve the monitoring of industrial assembly lines. At the back of the human eye is a specialised layer of cells called the retina, which captures light information. This information is then converted into electrical signals and sent via the optic nerve to the brain, where a visual image is produced.
