Biocompatible polymer-based sensors have unique advantages over semiconductor-carbon-based, and metal-based piezoresistive sensors because of the flexible nature, high gauge factor, and high bendability of the polymers. In this study, various compositions of biocompatible Poly(vinylidene fluoride-trifluoroethylene- chlorotrifluoroethylene) P(VDF-TrFE-CTFE) (TER)/poly(3,4-ethylene dioxythiophene) (PEDOT):poly(styrene sulfonate) (PSS) elastomer-electronic polymer blends were developed using cost-effective blending method for piezoresistive strain sensor. The TER /PEDOT:PSS polymer blend with an optimized blending ratio of 40/60 produced a gauge factor of around 680 with a high dielectric constant and a high mechanical strain of 221%. The TER/PEDOT:PSS polymer blend shows stable and repeatable response sensing signals up to 6500 bending cycles at a bending strain of 0.009 and checked for the duration of sixty days. The SEM analysis shows the penetration of the PEDOT:PSS particles between the backbone of TER polymer in the optimized TER/PEDOT:PSS polymer blend, which enhances the gauge factor of the TER/PEDOT:PSS blend sensors. Owing to high ductility and high sensitivity, our proposed elastomer-electronic polymer blend with ~0.18 mm thickness will find applications in wearable and electronic skin technology.

生物相容性聚合物基传感器比聚合物碳基和金属基压阻传感器具有独特的优势，因为聚合物具有柔韧性，高规格系数和高弯曲性。在这项研究中，生物相容性聚（偏二氟乙烯-三氟乙烯-三氟氯乙烯）P（VDF-TrFE-CTFE）（TER）/聚（3,4-乙烯二氧噻吩）（PEDOT）：聚苯乙烯磺酸盐（PSS）的各种成分弹性体-电子聚合物共混物是使用经济有效的压阻应变传感器共混方法开发的。TER / PEDOT：PSS聚合物共混物的最佳混合比为40/60，产生的规格系数约为680，具有高介电常数和221％的高机械应变。TER / PEDOT：PSS聚合物共混物在0.009的弯曲应变下显示出高达6500个弯曲循环的稳定且可重复的响应感测信号，并检查了六十天的时间。SEM分析显示，在优化的TER / PEDOT：PSS聚合物共混物中，PEDOT：PSS颗粒渗透到TER聚合物的骨架之间，这增强了TER / PEDOT：PSS共混物传感器的规格系数。由于具有高延展性和高灵敏度，我们建议的厚度约为0.18 mm的弹性体-电子聚合物共混物将在可穿戴和电子皮肤技术中得到应用。
