Abstract:
A pressure-sensitive variable-conductance analog sensor with tactile feedback actuatable by a single human finger, comprising;a housing; electrically highly conductive elements at least in-part within said housing; a depressible actuator retained by said housing and in-part exposed external to said housing for depression by a single human finger; a resilient snap-through dome-cap positioned within said housing and depressible with force from said actuator applied to said dome-cap to cause said dome-cap to snap-through and create a snap-through tactile feedback detectable by the finger depressing the actuator; and pressure-sensitive variable-conductance material positioned within said housing, said pressure-sensitive variable-conductance material electrically positioned as a variably conductive element between said highly conductive elements, said pressure-sensitive variable-conductance material further positioned for receiving force applied to said dome-cap.
