The present disclosure is directed to various mechanical logic gates. In one example a mechanical logic NOT gate system is formed which has a first pair of bi-stable buckling structures each being operatively connected at a first connection point thereof to one another, and also to a first rigid structure at second connection points, the first rigid structure being held stationary. A second pair of bi-stable buckling flexures is each operatively connected at first connection points thereof to each other and at second connection points thereof to a second rigid structure being held stationary. An output element is coupled a first one of each of the first and second pairs of bi-stable buckling structures. An input element is coupled to a second one of each of the first and second pairs of bi-stable buckling structures. The output element moves from a logic 1 position to a logic 0 position in response to movement of the input element from a logic 0 position to a logic 1 positions, respectively.
