Sharp eye on the money

Tom Shelley heads for Lancashire to look at bank note and coin recognition techniques that might well add the golden touch to many automated tasks


Film feels the pressure to change colour

A colour-changing film offers a fast way of assessing pressure variation between surfaces, and could be cheaper than electronic sensors. Lou Reade reports


The magic touch

Tom Shelley reports on why ‘feeling’ robots could outperform those solely dependent on vision systems


Linear progression

Astronomy and electronics are two beneficiaries of cutting edge linear motion technology. Lou Reade reports from the Linear Motion Masterclass


Meter makes a big noise

Tom Shelley reports on a step forward in noise measurement that not only reduces work, but also means problems get pinpointed quickly


Displays on contact lenses

Electronic displays built into contact lenses could in a few years be providing head up capabilities to both soldiers and motorists

A simple device for picking up and putting down microtubes – and an equally straightforward method of indicating which tube should be attended to next – enormously assists efficiency in biological ...


Silicon sensing

A technology used to produce smaller, more powerful microchips is helping to make a whole new generation of compact, robust sensors. Jonathan Ward reports



Screw-in device measures dew point inside

Brownell has a developed a device that can be screwed into the side of a container to measure the humidity inside, then show relative humidity, ambient temperature and dew point.


Making sense of sensors

Effective use of modern sensor technology can be as much about integration approach as about the physics of measurement. Jonathan Ward reports
