Abstract: A microstructure that detects the acoustic velocity of a fluid by employing microfabricated thin sensing elements that are primarily driven by viscous forces due to the fluctuating motion of a fluid, such as air in a sound field. The microstructures can be fabricated in an array to create a diaphragmless microphone. The microstructure and its components can be fabricated on a single or multilayer substrate with the use of masks.

Abstract: Microphones, microphone systems, and methods for capturing and processing sound are described. The microphones and microphone systems may adaptively change the direction from which sound is captured. The microphones and microphone systems avoid the need to provide arrays of microphones, while providing adaptive beamforming without a time delay between each channel of information, and multi-directional sound capture. A dependency between the frequency response and system size is also avoided.

Abstract: A microelectromechanical actuator, comprising: a substrate, having a surface; a conductive beam suspended parallel to the substrate, displaceable along an axis normal to the surface of the substrate; a center electrode on the substrate under the beam; a pair of side electrodes on the substrate configured, when charged, to exert an electrostatic force normal to the surface of the substrate on the beam that repulses the beam from the substrate, and exerts a balanced electrostatic force on the beam in a plane of the surface of the substrate, the center conductive electrode being configured to shield the beam from electrostatic forces induced by the side electrodes from beneath the beam, and the center electrode being configured to have a voltage different from a voltage on the beam, to thereby induce an attractive electrostatic force on the beam.

Abstract: A microelectromechanical (MEMS) transducer includes a substrate, a moveable electrode supported by the substrate, and a pair of fixed electrodes supported by the substrate, each fixed electrode of the pair of fixed electrodes being configured as a bias or sense electrode. The pair of fixed electrodes are disposed in a stacked arrangement. An end of the moveable electrode is configured for vibrational movement along the stacked arrangement during excitation of the moveable electrode. The pair of fixed electrodes are laterally spaced apart from the end of the moveable electrode to establish a capacitance indicative of the vibrational movement.
