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.
