Spray-on computers

Scottish scientists have developed a computer the size of a matchstick head, thousands of which can be sprayed onto patients to give a comprehensive analysis of their condition.

Speckled computing - some of the most advanced computing technology in the world - is currently being researched and developed by a group of Scottish experts. The individual appliances, or 'specks', will form networks that can be programmed like ordinary computers.

Spraying them directly onto a person creates the ability to carry out different tests at the same time, for example muscle movement and pulse rate. This allows a complete picture of the patient's condition to be built up quickly.
