“…These hysteresis errors caused by temperature could be reduced by implementing an equivalent sensing system with two SAWR elements manufactured on a single die [ 23 ]. However, even at 500 °C, the δ Hm of the two devices are still less than 5%, which is comparable with the results in [ 7 ] and indicates that these two sensors have good performance in high-temperature environments.…”

“…The relative errors ( e L ) between the measurement data and the linear fitting line in strain measurements is defined as [ 7 ]

where △ϕ(d) is the maximum deviation between the measurement data and the fitting curve, and Y FS is the full Y-scale range of the measurement, which equals to ϕ ( T,d = 4 mm)− ϕ ( T, d = 0). The calculated e L values of the two devices are presented in Table 1 .…”

“…Based on the change in resonance frequency, the extent of temperature variation and structure deformation of the SAW sensor could be evaluated. There have been many SAW strain sensors developed for SHM [ 5 , 6 , 7 ]. However, due to the limitation of the substrate materials, the working temperature of these sensors is always limited to below 150 °C.…”

Two Surface acoustic wave (SAW) resonators were fabricated on langasite substrates with Euler angle of (0°, 138.5°, 117°) and (0°, 138.5°, 27°). A dipole antenna was bonded to the prepared SAW resonator to form a wireless sensor. The characteristics of the SAW sensors were measured by wireless frequency domain interrogation methods from 20 °C to 600 °C. Different temperature behaviors of the sensors were observed. Strain sensing was achieved using a cantilever configuration. The sensors were measured under applied strain from 20 °C to 500 °C. The shift of the resonance frequency contributed merely by strain is extracted from the combined effects of temperature and strain. Both the strain factors of the two SAW sensors increase with rising ambient temperature, and the SAW sensor deposited on (0°, 138.5°, 117°) cut is more sensitive to applied strain. The measurement errors of the two sensors are also discussed. The relative errors of the two sensors are between 0.63% and 2.09%. Even at 500 °C, the hysteresis errors of the two sensors are less than 5%.

“…Yarn tension is often the key factor in the process of yarn production. [12][13][14][15] If too much force is supplied, the yarn will be snapped. If there is not enough force, the yarn will become loose and curled.…”

In this paper, the effect of the interdigital transducer (IDT) position parameters on the surface acoustic wave (SAW) yarn tension sensor sensitivity is investigated. The stress–strain characteristic of substrate was studied by the combination of finite element simulation and regression analysis method. According to this characteristic, the function relationship between the SAW yarn tension sensor sensitivity and the IDT position parameters was built using the regression analysis method. The monotonicity of the regression function was also given. On this basis, a novel sensitivity optimal scheme was proposed and solved by the quadratic programming method. Its solution demonstrates that the optimum sensitivity can be obtained when the IDT is 8.9 mm to the left side of the substrate and the IDT is 0.3 mm to the top edge of the substrate within a domain of the IDT position parameters. The SAW yarn tension sensor with corresponding IDT position parameters was fabricated to validate the correctness of the sensitivity optimal scheme. The measured results indicate that the SAW yarn tension sensor sensitivity can reach 813.69 Hz/g, which confirms that the novel scheme is effective.

“…However, this sensor system needs a reader to send and receive wave signals, which makes the measurement extremely sensitive to interference. Lu et al from Xidian University designed a compensated SAW sensor to measure the yarn tension [7]. The measurement range is no more than 1 N, and its structure is not suitable for installing in parachute ropes.…”

Heavy-equipment airdrops are mainly used to deliver relief supplies and heavy weapons. Given the heavy weight of the goods, the tension of the extraction and brake ropes of the parachute significantly affects the safety of the aircraft. On the basis of the measurement and installation characteristics of the parachute rope, this study designed the structure of a nondestructive pressure-type parachute rope tension sensor and set the location of the strain gauge patch using the ANSYS simulation software to obtain a high sensor sensitivity. The temperature error of the tension sensor is compensated, and the precision is improved using the LSSVM-PSO (Least Squares Support Vector Machine-Particle Swarm Optimization) algorithm. The developed tension sensor is applied to the extraction parachute test system to measure the traction of 2 and 8 m2 parachutes. Test results show that the maximum weight of the platform these two parachutes can draw and the effect of parachute opening can be calculated.
