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.
