Rothberg, addressing the boy as he would a peer, told him the best way to do that would be to create a tiny chemical sensor that could read electrical signals passing between brain cells.

Rothberg's contribution was to come up with a sensor that directly reads telltale electrical signals produced as DNA copies itself.

With no sight, it detects movement with a tiny sensor in its nose, which picks up the electrical current of its prey.

This microscopic scale and sensitivity allows the sensor to map a high-resolution image of electrical charge that occurs over the surface of a source material (for example a human finger), when it makes contact with a thin insulating surface (ie a plastic surface).

This is connected to a sensor that picks up changes in pressure and translates them into electrical signals.

The devices do not include electrical wiring or battery replacements, making it a likely candidate for powering remote sensor networks and medical-sensing technologies.

The agency also wants its sensor to identify individual humans using electrocardiography, which traces the heart's electrical activity.
