But instead of producing an electrical signal when it is tickled, the optical nose sneezes light.
They are used in some microphones to convert vibrations into an electrical signal.
The hogu sensors convert the force of a blow into an electrical signal, which is then sent to a laptop base station.
They turned an electroactive polymer into an actuator so that the material could change to exert force with an electrical signal, basically creating an exomuscle.
You are pushing on an electrical signal to motor the engine.

Light striking this detector liberates electrons from some of the silicon atoms, producing an electrical signal that is converted by the chip's electronics into a picture.
Chief technical officer Nigel Gilhespy says the fabric is made of five layers of fabric, three of which are conductive, which means they create an electrical signal and perform a high-tech function.
Even more surprisingly, they found that each receptor, located on the surface of a particular cell, is unique, and when activated by an odorant, triggers the cell to send an electrical signal to the brain.
The latch works by running an electrical current down a signal wire, through two switches.
Air France has said that Flight AF 447 sent an automatic signal indicating electrical problems while going through strong turbulence early in its 11-hour flight from Rio de Janeiro to Charles de Gaulle airport in Paris.
