Abstract: A system and method for detecting a failure of a fluid film bearing is disclosed. The system and method use one or more non-laser based strain transducers to detect changes in the frequency spectrum of the pressure of the fluid film at one or more locations in the bearing to identify failure or the risk of failure of the bearing. The system and can use metallic film, piezoelectric, and piezoresistive strain sensors to generate alarms when particular frequency bands become present in the strain frequency spectrum. The system and method can also generate strain orbit plots and perform waveform analysis of the time varying strains in the bearing housing caused by time-varying changes in the pressure of the fluid film.

Abstract: A load-sensing device is arranged in a package forming a chamber. The package has a deformable substrate configured, in use, to be deformed by an external force. A sensor unit is positioned in direct contact with the deformable substrate and is configured to detect deformations of the deformable substrate. An elastic element within of the chamber is arranged to act between the package and the sensor unit to generate, on the sensor unit, a force keeping the sensor unit in contact with the deformable substrate. The deformable substrate may be a base of the package, and the elastic element may be a metal lamina arranged between the lid of the package and the sensor unit. The sensor unit may be a semiconductor die integrating piezoresistors.

Abstract: The invention provides a piezoresistive electronic skin, a preparation method and a use thereof. The piezoresistive electronic skin uses carbon nanotube film as the conductive layer and uses materials provided with micro-nano patterns, such as polydimethylsiloxane, polyethylene terephthalate, polyvinyl alcohol, polyvinyl formal, polyethylene, and so on, as the substrate, enabling the substrate has advantages of high flexibility and being pliable, and it needs low operating voltage and little power consumption, but has high sensitivity and short response time. More importantly, the invention uses the patterned flexible substrate as the basis, greatly improving the sensitivity of electronic skin reacting to tiny applied force from outside. The invention also provides a capacitive electronic skin and a preparation method thereof. Further, the invention also provides a use of the piezoresistive electronic skin or the capacitive electronic skin on speech recognition, pulse detection, medical robot, etc.

Abstract: Even when a strain sensor chip and an object to be measured are bonded to each other by using a metallic bonding material such as solder, the metallic bonding material shows the creep behavior when used under high temperature environment of, for example, 100° C. or higher, and therefore, the strain detected by the strain sensor chip is gradually reduced, and the strain is apparently reduced. In the strain sensor chip mounting structure which is one embodiment of the present application, a strain sensor chip is fixed onto a surface to be measured of the object to be measured via a metallic bonding material. And, the metallic bonding material is bonded to a metallic film that is formed on a side surface of the strain sensor chip. In this manner, temporal change in a measurement error can be suppressed.

Abstract: An optically transparent force sensor that may compensate for environmental effects, including, for example, variations in temperature of the device or the surroundings. In some examples, two force-sensitive layers are separated by a compliant layer. The relative electrical response of the two force-sensitive layers may be used to compute an estimate of the force of a touch that reduces the effect of variations in temperature. In some examples, piezoelectric films having anisotropic strain properties are used to reduce the effects of temperature.
