“…It can be noticed that multifunctional sensors are often unable to balance functional diversity with single parameter (or mechanism) sensing performance. For example, the strain and pressure multimodal sensors developed by Keum et al exhibited a long response/recovery time of 227/232 ms and baseline drift in the cyclic stability test in pressure sensing; the bimodal sensors by all-inkjet-printing also failed to achieve high capacitive response sensitivity over a wide pressure measurement range. , Given that the main limitations present in this study focus on the static pressure response sensitivity and speed, future directions of work include the introduction of two-dimensional materials such as graphene and MXene to PZO membranes and the preparation of porous dielectric layers by the sacrificial template method. , This ensures the benefits of dual mechanism sensing while optimizing capacitive response performance.…”

To extend the application range of flexible pressure sensors and to be widely used as an economical and convenient way, researchers have made efforts toward high sensitivity, wide detection range, and low power consumption. However, most sensors can only work based on a single mechanism, thus limiting the sensing range and applicability. In view of this, we developed a dual-mechanism pressure sensor (DMPS) based on Ag nanowire/PDMS electrodes and ZnO nanoparticle-based force-sensitive membranes, which has a sandwich structure and complete flexibility under the effect of chemical bonding. It can simultaneously sense high-frequency dynamic pressure as well as static load by integrating piezoelectric and piezocapacitive effects, thereby complementing the inability of conventional piezoelectric-type sensors to continuously detect static pressure. The prepared flexible DMPS containing 20 wt % ZnO nanofiller has a pressure frequency-independent electrical output of about 2 V under 20 N force conditions and also has a long-term stability of more than 5000 pressure cycles. Moreover, it exhibits good linearity, repeatability, and stability in the 0–100 kPa detection range in the piezocapacitive mode. On the basis of multimechanism and modularity, the flexible DMPS was demonstrated for fruit quality monitoring, including avocado ripeness grading, tactile sensory gloves, and moisture loss assessment, indicating its promising applications in intelligent agricultural machines and wearable sensing systems.

“…When the applied pressure exceeds 0.5 kPa, the sensitivity exceeds that of conventional capacitive fiber pressure sensors (Figures k & S17 and Table S1). − Such an increase in sensitivity is even more pronounced under high pressures. More specifically, the sensitivity improves by 1081% within the pressure range of 10–25 kPa …”

Soft capacitive pressure sensors with high performance are becoming increasingly in demand in the emerging flexible wearable field. While capacitive fiber pressure sensors have achieved high sensitivity, their sensitivity range is limited to low-pressure levels. As fiber sensors typically require preloading and fixation, this narrow range of high sensitivity poses a challenge for practical applications. To overcome this limitation, the study proposes resistive-capacitive hybrid response fiber pressure sensors (HFPSs) with three-layer core−sheath structures. The trigger and sensitivity enhancement mechanisms of the hybrid response are determined through model analysis and experimental verification. By adjustment of the sensitivity enhancement range of the hybrid response, the sensitivity attenuation of HFPSs is alleviated significantly. The obtained results demonstrate that HFPSs have excellent characteristics such as fast response, low hysteresis, wide response frequency, small signal drift, and good durability. The hybrid response enhances the practical sensitivity of HFPSs for various applications. With enhanced sensitivity, HFPSs can effectively monitor pulse signals at preloads ranging from 0 to 22.7 kPa. This wide range of preloads improves the fault tolerance of pulse monitoring and expands the potential application scenarios of fiber pressure sensors.

“…Since some RGO nanosheets may slide and separate around during the stretching process, MnFe 2 O 4 particles fill the voids of RGO sheets, even acts like a sliding bead, facilitating slip between sheets, resulting in the high stability of the fabric during multiple stretching. [51][52][53] Figure 5(b) shows the piezoresistance behavior of fabric sensor under different tensile strains of 10%, 15%, 20% and 25% along the course of the fabric. The piezoresistance of the fabric sensor are almost identical among every strain interval, demonstrating good electromechanical stability of sensor.…”

Herein, a MnFe2O4/RGO knitted fabric derived from manganese waste was constructed by a simple in-situ assembled coating method, involving the incorporation of Graphene Oxide (GO) and manganese ferrite nanoparticles on polyester fabric, followed reducing by hydrazine hydrate. The reuse of manganese waste from the preparation of GO can reduce chemical waste emissions and endow the absorption performance. The coated particles possess certain magnetism can be attracted and securely collected in seconds, which is convenient for recycling. This fabric gives well microwave absorption with the maximum reflection loss (RL) of −58.6 dB at 9.1 GHz by a thickness of 1.9 mm. In addition, this fabric presents high stable strain sensing under 1000 stretching and bending cycles. Meanwhile, the resistance-deformation-velocity relationship is provided based on the structure, for the analysis of electromechanical behaviors. Moreover, the fabric has the capability for temperature sensing (TCR=−0.738%/°C), and fire alarm. As such, this fabric can be promising alternatives for a wide application on motion and temperature sensing, microwave blocking.
