Current years have witnessed the achievements of flexible force sensors, since they show great potentials in disease diagnosis, virtual reality and so forth. Conductive materials and the corresponding conductive networks are the two pivotal components that collaboratively determine the performances of flexible force sensors. Recently, some conductive force sensing materials that come into sight exhibit unique properties, but still not systematically concluded yet. Additionally, the diversity of conductive networks also has enormous effects on their force sensing performances. Regretfully, few associated reviews have summarized such response characteristics of conductive networks. In this review, initially, we summarize some conductive force sensing materials appeared recently, including conductive metal–organic frameworks, ionic deep eutectic gels, Then, we discuss the force sensing features of conductive networks designed from the “Network Structure Engineering”, which contains intrinsic morphologies and arrangement configurations of conductive components. Finally, we propose the future development trends of flexible force sensors from the perspective of both conductive materials and conductive networks.

用于柔性力传感器的导电材料和导电网络的开发


近年来，柔性力传感器取得了一定的成就，在疾病诊断、虚拟现实等方面展现出巨大的潜力。导电材料和相应的导电网络是共同决定柔性力传感器性能的两个关键组件。最近，一些进入人们视野的导电力传感材料表现出独特的性能，但尚未系统地得出结论。此外，导电网络的多样性也对其力传感性能产生巨大影响。遗憾的是，很少有相关评论总结传导网络的此类响应特征。在这篇综述中，我们首先总结了最近出现的一些导电力传感材料，包括导电金属有机框架、离子深共晶凝胶，然后，我们讨论了从“网络结构工程”设计的导电网络的力传感特性，其中包括导电元件的固有形态和排列配置。最后，我们从导电材料和导电网络的角度提出了柔性力传感器的未来发展趋势。
