Abstract: A microelectromechanical system (MEMS) sensor assembly comprises a substrate, a bump stopper extending from the substrate, and a sensor suspended relative to the substrate. The sensor is configured to move relative to the substrate, wherein the bump stopper is configured to restrain the sensor travel distance and prevent contact between the sensor and the substrate. The bump stopper has a surface facing the sensor, wherein an area of contact between the sensor and the surface is less than the total area of the surface.

Abstract: A low power consumption multi-contact micro electro-mechanical strain/displacement sensor and miniature autonomous self-contained systems for recording of stress and usage history with direct output suitable for fatigue and load spectrum analysis are provided. In aerospace applications the system can assist in prediction of fatigue of a component subject to mechanical stresses as well as in harmonizing maintenance and overhauls intervals. In alternative applications, i.e. civil structures, general machinery, marine and submarine vessels, etc., the system can autonomously record strain history, strain spectrum or maximum values of the strain over a prolonged period of time using an internal power supply or a power supply combined with an energy harvesting device. The sensor is based on MEMS technology and incorporates a micro array of flexible micro or nano-size cantilevers. The system can have extremely low power consumption while maintaining precision and temperature/humidify independence.

Abstract: A microelectromechanical systems (MEMS) scanning device comprising a torsional beam flexure that has a variable width in relation to a rotational axis for a scanning mirror. The geometric properties of the torsional beam vary along the rotational axis to increase a desired mode of mechanical strain at a location where a strain sensor is operating within the MEMS scanning device to generate a feedback signal. The torsional beam flexure mechanically suspends the scanning mirror from a frame structure. During operation of the MEMS scanning device, actuators induce torsional deformation into the torsional beam flexure to cause rotation of the scanning mirror about the rotational axis. The degree or amount of this torsional deformation is directly related to the angular position of the scanning mirror and, therefore, the desired mode of mechanical strain may be this torsional deformation strain component.

Abstract: A micro-electro-mechanical system (MEMS) package structure and a method for fabricating the MEMS package structure. The MEMS package structure includes a MEMS die (200) and a device wafer (100). A control unit and an interconnection structure (300) are formed in the device wafer (100), and a first contact pad (410) and an input-output connecting member (420) are formed on a first bonding surface (100a) of the device wafer (100). The MEMS die (200) is coupled to the first bonding surface (100a) through a bonding layer (500). The MEMS die (200) includes a closed micro-cavity (220) and a second contact pad (220). The first contact pad (410) is electrically connected to a corresponding second contact pad (220). An opening (510) that exposes the input-output connecting member (420) is formed in the bonding layer (500). The MEMS package structure allows electrical interconnection between the MEMS die (200) and the device wafer (100) with a reduced package size, compared to those produced by existing integration techniques. In addition, function integration ability of the package structure is improved by integrating a plurality of MEMS dies of the same or different structures and functions on the same device wafer.

Abstract: A system and/or method for utilizing mechanical motion limiters to control proof mass amplitude in MEMS devices (e.g., MEMS devices having resonant MEMS structures, for example various implementations of gyroscopes, magnetometers, accelerometers, etc.). As a non-limiting example, amplitude control for a MEMS gyroscope proof mass may be accomplished during normal (e.g., steady state) gyroscope operation utilizing impact stops (e.g., bump stops) of various designs. As another non-limiting example, amplitude control for a MEMS gyroscope proof mass may be accomplished utilizing non-impact limiters (e.g., springs) of various designs, for example springs exhibiting non-linear stiffness characteristics through at least a portion of their normal range of operation.
