Abstract:
1. Electromechanical device having an electrically conductive or semiconducting nano-cantilever wherein the nano-cantilever has a free end that is movable relative to an electrically conductive substrate of a circuit, a power source connected in the circuit for providing a voltage between the substrate and the nano-cantilever to effect bending movement of the nano-cantilever relative to the substrate, and a feedback control for varying the voltage between the substrate and the nano-cantilever in response to the position of the nano-cantilever relative to the substrate wherein two stable positions of the nano-cantilever and a hystersis loop in the current voltage space between a pull-in voltage and a pull-out voltage are provided.
