摘要： Methods, apparatuses and systems for a sensing deformation in a surface are disclosed herein. An example device may include a first sensor configured to mechanically couple to a first point and a second point on a surface. The first point and the second point may be located across an opening of a groove on the surface. An electrical property of the first sensor may be configured to change in response to a variation in the distance between the first point and the second point.

摘要： The present invention relates to a sensing system that, in a preferred embodiment, can be readily integrated into load-lifting structures (such as wings and landing gears) to provide real-time DPHM and obviate/mitigate catastrophic problems. Broadly, the present sensing system combines at least one shim portion with at least one nanogenerator such as a TENG or a PENG. A major advantage of the present sensing system is that it combines in a single structure the following functions: (a) gap management in the component in which the sensing system is installed, (b) collection/storage of measured data for the component in which the sensing system is installed, (c) harvesting/storing energy from operation environment of the component in which the sensing system is installed (e.g., DPHM data when the present sensing system is used for assessment of an aircraft's structural conditions), and (d) wireless transmission of measured data for the component in which the sensing system is installed to a user interface.

摘要： A microelectronic chip device includes a semiconductor substrate and multiple on-chip strain sensors (OCSSs) constructed on the substrate at various locations of the substrate. The OCSSs may each include multiple piezoresistive devices configured to sense a strain at a location of the various locations and produce a strain signal representing the strain at that location. A strain measurement circuit may also be constructed on the semiconductor substrate and configured to measure strain parameters from the strain signals produced by the OCSSs. The strain parameters represent the strains at the various location. Values of the strain parameters can be used for analysis of mechanical stress on the chip device.

摘要： A strain sensor may have a conductive elastic yarn including a first fiber having a predetermined length and a shape of a fiber yarn and a second fiber having electrical conductivity and a sheet shape. The strain sensor may have a pair of wiring members electrically connected to both ends of the conductive elastic yarn. The conductive elastic yarn, with the second fiber wrapped around the first fiber, is twisted in a coil shape.

摘要： A cable barrier system is managed by a cable barrier management system including a management system controller having a management processor and a plurality of turnbuckle subsystems joined to respective barrier cables to provide pretension. Each of the turnbuckle subsystems has a strain gauge mounting zone, and strain is communicated from a strain gauge circuit to the management processor. The controller is configured to determine excess strain events. Strain event data is sent via a wireless data communications interface to a remote recipient computing device.

摘要： Eyewear including a sensor integrated into frame of eyewear. In one example, the sensor comprises a strain gauge, such as a metallic foil gauge, that is configured to sense and measure distortion of the frame when worn by a user and under different force profiles, by measuring a strain in the frame when bent. The measured strain by strain gauge is sensed by a processor, and the processor performs dynamic calibration of image processing based on the measured strain. The distortion measured by the strain gauge is used by the processor to correct calibration of the cameras, and the displays.

摘要： An anomaly detection system that outputs an anomaly detection signal before a safety valve of a secondary battery is opened is provided. The anomaly detection system includes a strain sensor, a memory, and a comparator. The memory has a function of retaining an analog potential, and the comparator has a function of comparing a potential output by the strain sensor and the analog potential retained by the memory. The strain sensor is attached to the secondary battery before use, and a predetermined potential is retained in the memory. When a housing of the secondary battery expands while the secondary battery is used, and the potential output by the strain sensor becomes higher (or lower) than the predetermined potential, an anomaly detection signal is output.
