“…This value can be used to compare the relaxation behaviors of different systems. 68 A quasi-static test can also be repeated (cyclical test) in order to check if the relaxation behavior is repeatable. Muth et al calculated for their silicone elastomer-based sensor that the response of the resistance for strains below the yield point did not exhibit an overshoot, and even though the sensor did not return to the initial value after the unloading, it always returned to a value within 10% of the original (Figure 8).…”

Piezoresistive strain sensors dominate the field of soft elastomer sensors, with many interesting findings and applications. Nevertheless, the methods of characterizing the performance of the sensor differ in each study, leading to different conclusions and comparing with the different sensor systems is challenging. In this attempt, the most important characterization methods of the sensor response are being presented and some cases of elastomer strain sensor are being highlighted. Furthermore, the different materials options for elastomer strain sensors are being shown with a special section for the rapidly growing field of additive manufacturing and 3D printing. Except from the material choices and testing methods, different applications of the strain sensor are presented. From the biomedical field, these soft sensors find

The crosslinking of SR chains makes the SR composites obtain excellent elasticity, [12][13][14] resulting in the quick recovery of the extended SR composite samples back to their original state after the releasing of external force.…”

Stretchable conductive silicone rubber (SR) composites are important in wearable electronic devices and the crosslinking of SR composites is necessary for their applications. But the effect of the crosslinking reaction on the electrical conductivity of SR composites is rarely reported. In this article, the effect of crosslinking reaction on the electrical conductivity of SR composites filled with conductive carbon black, carbon nanotubes, and graphene are studied. The crosslink density of SR composites increases with increasing curing time, but the electrical conductivity decreases sharply at the early stage of crosslinking, especially for SR/conductive carbon black composite, which is ascribed to the reaggregation of conductive nanofillers in SR during the crosslinking process. The elastic modulus of the three SR composites gradually increases while the elongation at break decreases with increasing curing time, and the SR/carbon black composite shows ultra‐high elongation at break (1578%). In addition, SR/graphene composite is more sensitive to the extension strain than SR/carbon black and SR/carbon nanotubes composites, and its gauge factor is 414 at the strain ranges of 3–25%. This research work brings a new method to optimize the crosslinking structure of conductive SR composites.

“…The ideal conductive materials should be flexible, conductive, responsive, and durable, stable and biocompatible . Carbon material has certain mechanical softness, outstanding flexibility, and excellent chemical stability, and is one kind of the ideal materials for the preparation of soft sensors. Among them, carbon nanotubes (CNTs) have high elastic modulus, large aspect ratio, excellent electrical properties, and high temperature resistance, but CNTs have high surface energy and are difficult to disperse, it is necessary to functionalize the CNTs or add some surfactants.…”

Smart wearable flexible sensors with high sensitivity and stability are still challenging nowadays when used for human motion detection, personal health monitoring, or artificial electronic skins. Here, a sensor assembled in a face‐to‐face manner based on fabric is proposed, firstly polyaniline (PANI)/nanonickel (Ni NPs)/COOH‐functionalized MWCNTs (COOH‐MWCNTs) conductive paste is prepared and printed on the cotton fabric. Then the printed fabric is assembled to be a flexible sensor which has double conductive layers. According to the analysis of the scanning electron microscopy, energy‐dispersive spectroscopy, X‐ray diffraction, and Fourier transform infrared spectroscopy, the synergistic performance of PANI, Ni NPs, and COOH‐MWCNTs is demonstrated. When the pressure is 0–0.1 kPa, gauge factor (GF) is 12.96 kPa−1, and when the pressure is 0.1–1 kPa, the GF is 1.33 kPa−1, indicating superior sensitivity of the sensor compared to traditional textile‐based sensors. It also displays quick response time of 0.2 s and recovery time of 0.3 s. The as‐prepared sensor can effectively monitor human micro motions like face, eye, and fingers movements, and it can also transmit electrical signals agilely by indirect contact. Moreover, a large‐area sensor spatial array is fabricated, and the test indicates the sensor can recognize spatial response.
