The result is a probe that can easily be picked up by medics and held close to the patient. Wires attached to the back of the probe lead to a computer that translates the electrical signals into a picture of the heartbeat or brainwave. A test version developed by the team was the size of a watch and worn on the wrist. The production version will be of a similar size but will not touch the skin.

So, not only is remote, it is small. There are other applications, too. They hope to be able to use an array of these devices to generate maps of heart and other activity, all non-invasively.

Even better, it has applications in electronics, as well.
