  • Patent number: 8436637
    Abstract: A nanomechanical device, operating as a reprogrammable logic gate, and performing fundamental logic functions such as AND/OR and NAND/NOR. The logic function can be programmed (e.g., from AND to OR) dynamically, by adjusting the operating parameters of the resonator. The device can access one of two stable steady states, according to a specific logic function; this operation is mediated by the noise floor which can be directly adjusted, or dynamically tuned via an adjustment of the underlying nonlinearity of the resonator, i.e., it is not necessary to have direct control over the noise floor. The demonstration of this reprogrammable nanomechanical logic gate affords a path to the practical realization of a new generation of mechanical computers.

  • Publication number: 20110187297
    Abstract: A mechanical device capable of switching between two states is described. The device may include a micromechanical resonator with two distinct states in the hysteretic nonlinear regime. The devices can be used as a low-power, high-speed mechanical switch integrated on-chip with silicon circuitry.
