Display area force sensing using Bragg grating based wave guide sensors

An electronic device includes an input surface area for receiving a force applied by a user and one or more optical waveguides that include Bragg gratings. The optical waveguide or waveguides is operatively affixed to the input surface area. At least one light source is optically coupled to the opti...

description An electronic device includes an input surface area for receiving a force applied by a user and one or more optical waveguides that include Bragg gratings. The optical waveguide or waveguides is operatively affixed to the input surface area. At least one light source is optically coupled to the optical waveguide or waveguides. At least one wavelength interrogator is coupled to the optical waveguide or waveguides.
