The sensor further includes a voltage generator that generates a first voltage across the first Schottky diode and a second voltage across the second Schottky diode. When the first Schottky diode and the second Schottky diode are subjected to different strain, the integrated circuit measures the values of the currents flowing through the first Schottky diode and the second Schottky diode to determine the strain on an element where the first Schottky diode and the second Schottky diode are attached.

摘要： A SAW based sensor apparatus utilizing semi-synchronous SAW resonator having a single resonance at Bragg frequency with very high quality factor is disclosed. The semi-synchronous SAW resonator includes at least one inter-digital transducer, which generates and receives surface acoustic wave and a number of grating reflectors, which reflect the surface acoustic wave and generate a standing wave between the reflectors, The interdigital transducer and the grating reflectors can be fabricated on a substrate (e.g., quartz) by photolithographic process. The resonance condition is independent of transducer directivity and reflection coefficient per finger. Such a SAW based sensor apparatus having three semi-synchronous SAW resonators can be utilized for measuring pressure and temperature for a wireless tire-pressure monitoring system.

摘要： A patterned dielectric elastomer actuator is disclosed which includes a series of thin parallel elastomer filaments, separated by certain distances sandwiched between a pair of rigid electrodes. The elastomer filaments and air acts as a patterned dielectric layer. The elastomer filaments can compress laterally from a circular cross-section to an elliptical shape when a voltage is applied between the rigid electrodes. The elastomer filaments can touch laterally, which implies no further squeezing in order to provide a minimal secure distance between the rigid electrodes. The dielectric elastomer actuator can be fabricated utilizing a reel-to-reel fabrication process with the thin elastomer filaments fabricated ahead of time, by extrusion techniques and cured completely before storing on reels.

摘要： A system for detection of stress and deformation in a structural asset, for instance, one of reinforced concrete. An area on the asset may have a structure interface, such as a patch, attached to it with a fastening mechanism which may be a layer of an epoxy or other material, or be items such as screws, bolts, welds, or the like. One or more surface acoustic wave (SAW) strain sensors may be attached to the interface with an adhesive layer of epoxy or other material, or with mechanical items. Stress may be transmitted by the interface to the strain sensors. The sensors may be interrogated with a wire or wireless reader to obtain strain measurements. The measurements may indicate stress and deformations such as bulges and breaks in the asset. The measurements may also be a basis for determining location and extent of the stress and deformations.
