Utilizing Multilayer Design of Organic-Inorganic Hybrids to Enhance Wearable Strain Sensor in Humid Environment

Self-Healable, Superhydrophobic, and Flexible Strain Sensor Based on Polyurethane Composite for Underwater Sensing

“…In addition, when the load ratios are too high, the fiber surface has formed a complete rGO shell, so the excess rGO cannot continue to be adsorbed on the SS-PU fibers uniformly, so the fibers’ surfaces become rougher. Notably, the shell formed by rGO on the surface of SS-PU fibers endows the fibers with electrical conductivity, which is the basis for the sensing performance of the fiber films . In order to study the effect of rGO load ratio on sensing performance, an electrochemical workstation is used to characterize the sensing performance of the material.…”

“…Notably, the shell formed by rGO on the surface of SS-PU fibers endows the fibers with electrical conductivity, which is the basis for the sensing performance of the fiber films. 43 In order to study the effect of rGO load ratio on sensing performance, an electrochemical workstation is used to characterize the sensing performance of the material. Figure S4a−d corresponds to the sensing performance test results of SS-PU/rGO when the ultrasonic treatment times are 5, 10, 20, and 30 min, respectively.…”

A double-crack structure for bionic wearable strain sensors with ultra-high sensitivity and a wide sensing range

“…Furthermore, people can arbitrarily arrange them according to the requirements of measurement conditions due to the various structures of flexible sensors. At present, flexible strain sensors are extensively used in the development of electronic skin, 10–13 healthcare, 14,15 voice recognition, 16,17 sports equipment, 18,19 triboelectric nanogenerators, 20 textiles, 21,22 aerospace, 23 environmental monitoring 24,25 and other fields. 26,27 Generally, the sensing performance of flexible strain sensors can be evaluated using various performance parameters such as sensitivity [gauge factor (GF)], stretchability (sensing range), linearity, hysteresis, response time, and dynamic stability.…”

Flexible Actuators with Hygroscopic Adaptability for Smart Wearables and Soft Grippers

“…However, these actuators are limited to thermal expansion and increasing their deformation further is difficult. Consequently, humidity-responsive flexible actuators ,,− are readily available, eco-friendly, and cost-effective. By optimizing material performance and enhancing spatial structure, their actuation performance and high-degree-of-freedom deformation have been improved.…”
