122 Optically controlled MEM switches US09429234 1999-10-28 US06310339B1 2001-10-30 Tsung-Yuan Hsu; Robert Y. Loo; Greg Tangonan; Juan F. Lam
An optically controlled micro-electromechanical (MEM) switch is described which desirably utilizes photoconductive properties of a semiconductive substrate upon which MEM switches are fabricated. In one embodiment the bias voltage provided for actuation of the switch is altered by illuminating an optoelectric portion of the switch to deactivate the switch. In an alternative embodiment, a photovoltaic device provides voltage to actuate the switch without any bias lines at all. Due to the hysteresis of the electromechanical switching as a function of applied voltage, only modest variation of voltage applied to the switch is necessary to cause the switch to open or close sharply under optical control.

136 Piezoelectric multiplexer US14513021 2014-10-13 US09245704B2 2016-01-26 Lizon Maharjan; Babak Fahimi; Daniel Christopher Dial; Joseph Hearron; Job Timothy Brunet; Arash Hassanpour Isfahani; Carlos Caicedo-Narvaez
A piezoelectric multiplexer includes an actuator and multiple piezo-morph beams. The actuator includes an actuator conducting head and an actuator stem, and each piezo-morph beam includes a conducting beam contact head and a beam stem manufactured out of piezo-morph material. A control voltage is selectively applied to electrical contacts coupled to the beam stems to create a piezoelectric effect that bends the selected piezo-morph beam and creates an electrical connection between its contact head and the conducting head of the actuator. A control circuit with a controller signals which piezo-morph beam to connect to the actuator. This multi-piezo-morph-beam piezoelectric multiplexer can be affixed to the electrical terminals of different electrical components (e.g., a transistor) to create an electrical cell that can be manufactured on a semiconductor chip or in a microelectromechanical system (MEMS) device.

A method of making an integrated texture sensor for sensing a texture is described. In one embodiment, the method is directed to a sensor that that is protected from external contaminating particulates and will self-equalize using air from outside the sensor. Further combinations of such protection among various membrane switches, in combination with various types of membranes, is described. In another embodiment, a method of making a skin-texture sensor for sensing a skin texture having a plurality of ridges and a plurality of valleys is described, such that when completed, applying a ridge of the texture to a membrane switch will cause flexure of the membrane resulting in a contact between the lower electrode and the upper electrode, the contact establishing an electrical communication between said one of the row lines and said one of the column lines, whereas disposing a valley of the texture over said each membrane switch will not result in the contact between the lower electrode and the upper electrode.
