Glass Gorilla Glass has become a thermometer

Researchers from the Technical University of Montreal and the company managed to build in Corning glass screens smartphones temperature sensor working on the principles of photonics. In photonic devices instead of electric current and the wires used photons moving along the optical waveguides. waveguide circuit was engraved in the glass Gorilla Glass, Corning production with a laser.

The temperature sensor is a Mach-Zehnder interferometer whose parameters vary with glass deformation by heat. By raising the temperature of the strain can be determined. Also the temperature sensor caused by researchers another glass waveguide structure that reflects infrared radiation. Unique pattern structure may allow the identification of a specific instance of the device.

Glass Gorilla Glass, according to researchers, provided the lowest level of losses, while the smallest and highest manufacturing quality and length of the waveguides all species tested glasses. With proper investment of funds, they believe, the production of such glasses with sensors could begin within a year. Researchers are looking for partners among manufacturers.
