Latest Patents
Changhong Ke holds a patent for a nanoelectromechanical bistable cantilever device. This device features an electrically conductive nano-cantilever that has a free end movable relative to an electrically conductive substrate, such as an electrode of a circuit. The circuit includes a power source connected to the electrode and the nano-cantilever, allowing for the application of a pull-in or pull-out voltage. This voltage induces bending movement of the nano-cantilever relative to the electrode. The device is designed to provide two stable positions of the nano-cantilever, creating a hysteresis loop in the current-voltage space between the pull-in and pull-out voltages. The first stable position occurs at a sub-nanometer gap with a stable tunneling electrical current, while the second position is achieved with a pull-out voltage and minimal tunneling current. This innovative device has potential applications in scanning probe microscopy, ultrasonic wave detection sensors, NEMS switches, random access memory elements, gap sensors, logic devices, and bio-sensors.
