High Compliance Capacitive Sensor

Sensors that rely on changes in capacitance are used in a very large number of important electronic products and systems. When detecting small motion, flow, or sound pressure, the performance of the sensor is normally improved when the effective stiffness between the moving and fixed electrodes is reduced. In sensitive microphones, the use of highly...

Interdigitated Comb Fins

This invention provides a method of creating interdigitated fins on a planar microstructure that is intended to deflect in the direction normal to its plane. The interdigitated fins consist of one set of fins that are attached to the planar microstructure and move with it as it moves out of plane. The other set of fins are normally attached to a fixed...

Miniature Non-Directional Microphone

This technology consists of a microphone diaphragm having a mechanical sensitivity that does not diminish as the area of the diaphragm is reduced. The diaphragm is compliantly suspended over an enclosed air volume having a vent port, wherein an effective stiffness of the diaphragm with respect to displacement by acoustic vibrations is controlled principally...

Robust Diaphragm for an Acoustic Device

This technology involves a microphone diaphragm that is connected to the surrounding structure through an internal supporting structure. The internal supporting structure of the diaphragm provides a combination of torsional and translational stiffeners, which resemble a number of crossbars. These stiffeners brace and support the diaphragm motion, thus...

Surgace Micromachined Dif-ferential Microphone

This invention consists of a microphone that can be fabricated with surface micromachining. In typical micromachined microphones, it is necessary to incorporate a significant volume of air behind the microphone diaphragm in order to prevent the back volume air from impeding the motion of the diaphragm. The air behind the diaphragm acts as a linear spring...

High-Order Directional Microphone Diaphragm

This invention consists of a miniature microphone diaphragm having a response that is highly dependent on the direction of the incident sound. A primary advantage of this invention over existing approaches is that this concept enables the fabrication of a single, miniature microphone diaphragm that achieves a second-order (or higher-order) directional...

Differential Microphone

This technology provides an acoustic sensing device or directional microphone having greater sensitivity and reduced noise. The directional microphone or acoustic sensor comprises a rigid, one micron thick polysilicon membrane having dimensions of approximately 1 mm×2 mm. The membrane is supported upon its central axis by beams having torsional...

Optical Differential Microphone

This invention involves a differential microphone that utilizes an optical means of converting the sound-induced motion of the diaphragm into an electronic signal. The majority of high-performance microphones, and particularly miniature microphones used in cellular telephones and hearing aids, use capacitive sensing to detect the diaphragm motion. This...
