柔性压力传感器可以附着在人体皮肤感知外界压力信号,且具有传感范围广、响应时间短、灵敏度和耐久性高等特点,因此被广泛应用于电子皮肤和人机交互等领域。柔性压力传感器通常由柔性基底、活性材料、导电电极组成。其中,一种或多种活性材料通过与柔性基底复合形成传感材料,其受外界刺激产生的变形会引起阻值等变化,进而实现传感功能。此外,通过引入微结构可增加传感材料的可压缩性以及对微小压力的敏感度,提升传感性能。本文围绕薄膜和织物两类基底,综述了在其中掺杂碳基、金属基与黑磷基等活性材料的柔性压力传感器的研究,重点论述了不同传感器的制备方法、机电性能与应用场景,总结了各类传感器的优缺点。在此基础上,对未来智能可穿戴柔性压力传感器如何实现宽范围压力检测、商业化以及制作流程无毒化与长时期生物相容性实验等方面的研究做出了展望。 |

Flexible pressure sensors can be attached to the human skin to sense external pressure signals, and have the characteristics of wide sensing range, short response time, high sensitivity, and durability. Therefore, they are widely used in the fields of electronic skin and human-computer interaction. Flexible pressure sensors are usually composed of flexible substrates, active materials and conductive electrodes. Among them, one or more of the active materials form a sensing material by compounding with a flexible substrate, and its deformation under external excitation will cause changes in parameters such as resistance, thereby achieving sensing function. In addition, by introducing microstructure, the compressibility and sensitivity to small pressure of the sensing material can be increased, and its sensing performance can be improved. In this paper, the research progress in flexible pressure sensors doped with carbon-based, metalbased, and black phosphorus-based active materials on film and fabric substrates was reviewed. The preparation methods, electromechanical properties and application scenarios of different sensors were discussed, and the advantages and disadvantages of various sensors were summarized. On this basis, the research on how to achieve wide-range pressure detection, commercialization, non-toxicity of the production process and long-term biocompatibility experiments of smart wearable flexible pressure sensors in the future is prospected. |
