Have you ever wondered how speed guns measure the speed of moving vehicles or how an athlete's sprint speed is recorded? Normally these speed sensors work with radar or laser technology to bounce back ...

As the quantified self movement continues to pick up momentum, the range of consumer devices tracking physiological signals is set to expand. But harvesting bio-signals requires specialist kit — which ...

[Edward], creator of the Cave Pearl project, an underwater data logger, needed a way to measure temperature with a microcontroller. Normally, this problem is most easily solved by throwing a ...

A sensor chip controlled not by wires and transistors, but by a living slime mould marks an important step towards more widespread use of biologically-driven components and devices, researchers say.
