Abstract: A light emitting key is disclosed. A through hole is made through piezoresistive layer; a light source is arranged under the bottom of the light emitting key. When the light source is turned on, light beams shall emit out of the top substrate. The light emitting effect of the key facilitates it to be used in a dark area such as an aircraft flying in the night sky.

Abstract: A D/A integrated pressure key for a keyboard is disclosed. A digital signal output first when a pressure is applied on the single key, and then an analog signal output while applying a bigger pressure over the same key. The magnitude of the analog signal output is positively related to the magnitude of the pressure applied on the integrated pressure key.

Abstract: A fast response force sensor is disclosed. The fast response force sensor comprises a solid-state bonding (SSB) spacer and piezo material therein. The SSB spacer is sandwiched between a top stack and a bottom stack of the force sensor. The SSB spacer maintains a fixed relative position between a top stack and a bottom stack of the force sensor when a fixed force is applied or removed. The SSB spacer is in solid state and shall not be significantly deformed while being depressed by a user, and therefore the response time of an output signal is vastly determined by the properties of the piezo material of the force sensor when a force is applied against the force sensor. Therefore, a fast response force sensor can respond quickly to a force applied against it.
