Modeling and validation of mechanoluminescent strain sensing mechanism at quasi-static loading ratesMechanoluminescencePersistent luminescenceModelAfterglowQuasi-staticMechanoluminescence (ML) sensors offer full-field strain/stress measurements and have the advantages of easy implementation, non-invasiveness, and low...
Their sensing mechanism is based on the changes in the relationship between their electrical resistance or capacitance and the strain exerted on them as a result of changes in the flexion of the joints in the hand. This creates a data glove that is textile, accurate, and light weight. ...
response time (~65 ms), small hysteresis, and superior durability (>2000 cycles). Subsequently, the sensing mechanism of the sensor was studied. Distributed microcrack propagation based on the “island-bridge” structure was explained in detail, and its influence on the strain-sensing behavior o...
The sensing mechanism also exhibits high linearity, as well as insensitivity to bending and twisting deformations—features that are important for soft device applications. To demonstrate the potential impact of our technology, we construct a sensor-integrated, lightweight, textile-based arm sleeve that...
Despite the high sensitivity offered by the cracking mechanism, the working range of these sensors often falls short of the useful sensing range for wearable electronics. Depositing metals on rough elastomer surfaces has been used as a strain-engineering strategy to improve the working range of ...

The elastomer substrate is used to pre-mount the sensors, making field installation easier, increasing the range of the sensors, allowing strain sensors to measure compression and elongation, and providing a mechanism whereby the sensors can be protected from failure due to excess strain. The ...
An intensity based sensor uses losses createdby longitudinal misalignment as a sensing mechanism and has a maximumoperating temperature of 700°C. An interferometric based sensor makes use of aFabry-Perot cavity created by aligning two fibers in a splice tube with a small gapin between. The ...
We demonstrated a linearized wavelength interrogation system of fiber Bragg grating (FBG) strain sensors, based on a wavelength-swept active mode locking (AML) fiber laser. Since the wavelength sweeping mechanism of the AML fiber laser does not depend on the wavelength selecting filter, we can eas...
The diagram shows the cross-section and the working mechanism of the chip. When vacuum pressure is applied to the annular vacuum chamber, the wall of the annular vacuum chamber deflects outward, stretching the internal suspended film and the adherent cells on it. The cells on the membrane are...
