Spray-on gadgetry isn't exactly new, but the possibility of spritzing a computer on your epidermis most certainly piqued our interest. A team of Scottish scientists have reportedly "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." The device(s) joins the ever-growing array of communication-enabled health sensors aimed at helping the elderly stay in contact with their doctors even in remote locations, and can compute a variety of inputs such as blood pressure, muscle movement, and pulse rate. The technology, dubbed speckled computing, can even be rigged to transmit information via radio waves, meaning that a full-fledged diagnostic report could get a whole lot less invasive if this stuff pans out.
