Soft-strain-based sensors are being increasingly used across various fields, including wearable sensing, behavior monitoring, and electrophysiological diagnostics. However, throughout all applications, the function of these sensors is limited because of high sensitivity, high-dynamic range, and low-power consumption. In this paper, we focus on improving the sensitivity and strain range of the soft-strain-based sensor through structure, surface, and sensitive unit treatment. Nanosilver (Ag)-coated hydroxyl-functionalized multi-walled carbon nanotubes (OH-f MWCNTs) were explored for highly acute sensing. With stretching and depositing methods, Ag@OH-f MWCNTs and polydimethylsiloxane (PDMS) are fabricated into a wrinkled and sandwich structure for a soft-strain-based sensor. The electronic properties were characterized in that the gauge factor (GF) = ΔR/R0 was 412.32, and the strain range was 42.2%. Moreover, our soft-strain-based sensor exhibits features including flexibility, ultra-lightweight and a highly comfortable experience in terms of wearability. Finally, some physiological and behavioral features can be sampled by testing the exceptional resistance change, including the detection of breath, as well as facial and hand movement recognition. The experiment exhibits its superiority in terms of being highly sensitive and having an extensive range of sensing.

用于可穿戴传感器的镀银碳纳米管的皱纹结构网络。

基于软应变的传感器正越来越多地用于各个领域，包括可穿戴传感，行为监控和电生理诊断。但是，在所有应用中，由于高灵敏度，高动态范围和低功耗，这些传感器的功能受到限制。在本文中，我们专注于通过结构，表面和敏感单元处理来提高基于软应变的传感器的灵敏度和应变范围。研究了纳米银（Ag）涂层的羟基官能化多壁碳纳米管（OH-f MWCNTs）的高度敏锐感测。通过拉伸和沉积方法，Ag @ OH-f MWCNT和聚二甲基硅氧烷（PDMS）被制成皱纹和夹心结构，用于基于软应变的传感器。电子特性的特征在于，表观系数（GF）＝ΔR/ R 0为412.32，应变范围为42.2％。此外，我们的基于软应变的传感器还具有灵活性，超轻量级和在舒适性方面非常舒适的体验。最后，可以通过测试异常的阻力变化来采样一些生理和行为特征，包括呼吸检测以及面部和手部动作识别。该实验在高度灵敏和广泛的感测方面显示出其优越性。可以通过测试异常的阻力变化来采样一些生理和行为特征，包括呼吸的检测以及面部和手部动作的识别。该实验在高度灵敏和广泛的感测方面显示出其优越性。可以通过测试异常的阻力变化来采样一些生理和行为特征，包括呼吸的检测以及面部和手部动作的识别。该实验在高度灵敏和广泛的感测方面显示出其优越性。
