A mouse trap based on a compliant bistable mechanism (BM) is developed in this investigation. The gripping arms of the trap are the addition to the BM. Catch and release operation of the trap are accomplished by snap-through behaviors of the BM. Two stable equilibrium positions of the BM are correspondent to the baiting and gripping configurations of the trap. The proposed mechanism has no movable joints and gains its mobility from the deflection of compliant members. Device complexity is reduced by integration of jaws and gripping arms with the BM. Utilizing the snap-through behavior of the BM, self-closing function for catching mouse is attained without additional locking parts or latches. Therefore, the catch action is autonomous and does not require additional energy input to hold the trapped mouse. Analytical models are developed for design of the device. Prototypes of the mechanism are fabricated by a simple three dimensional printing process. The characteristics of the mechanism are verified by experiments. A “mouse” is caught and released though the linear motion of the BM. The mouse strap can also be used for assembly and disassembly of industrial parts.
