摘要： Systems and methods are provided for monitoring the structural integrity of a vehicle. In particular, systems and methods are provided for using transducers positioned at various location in and on a vehicle to measure parameters related vehicle structural health. In various implementations, the integrity of the vehicle frame and the integrity of the vehicle body are monitored using a multi-axis accelerometer and/or microphone. The use of transducers for monitoring can replace time-consuming and expensive manual inspections.

摘要： Aspects of the present disclosure relate to a piezoelectric device having at least one piezoelectric element, which has a support plane oriented to a force introduction element, wherein in the event of a thermal loading of the piezoelectric device in the support plane, expansion differences between the piezoelectric element and the force introduction element occur. To compensate for shear loadings, at least one transition element is arranged between the piezoelectric element and the force introduction element, the E-module of which is smaller than the E-module of the piezoelectric element in the support plane.

摘要： A mechanical link for microelectromechanical and/or nanoelectromechanical structure, includes a mobile component, a fixed component extending on a plane, and apparatus for detecting displacement of the mobile component relative to the fixed component. The mechanical link includes: a first link to the fixed component and mobile component, allowing rotation of the mobile component relative to the fixed component about an axis of rotation; a second link connecting the mobile component to the detection apparatus at a distance and perpendicular to the axis of rotation; a third link to the fixed component and detection apparatus, guiding the detection apparatus in a direction of translation in the plane; wherein the combination of the second link and third link can transform rotational movement of the mobile component into translational movement of the detection apparatus in the direction of translation. The detection apparatus includes a piezoresistive/piezoelectric strain gauge, resonance beam, capacitance, or combination thereof.

摘要： A force sensing device is mounted on a tool to sense force, particularly quasi-static and static forces. The force sensing device includes at least one a sensor. A piezoelectric element in the sensor includes a driving portion and a sensing portion. A first voltage is input to the driving portion to generate a vibration in the piezoelectric element and a second voltage in response to the vibration is output from the sensing portion. The second voltage output from the sensing portion is changed as the vibration in the piezoelectric element is suppressed by an external force acting on the force sensing device so variation of the second voltage can be used to measure the external force.
