摘要

在这项工作中，我们展示了一种基于丝基衬底的柔性自供电压力传感器的开发。丝是能从自然界获得的最薄、最坚韧的纤维。基于这些高贵的特性，它在医疗保健、人机界面和类人机器人方面的应用是非常需要的。在可见光范围(400~700nm)内，丝绸与聚偏氟乙烯-共三氟乙烯合成的薄膜压电系数为6.24pm/V，透过率高达88%。所获得的传感器具有显著的线性，在宽范围(~500kPa)内灵敏度为70Pa−1，并且具有超过10,000次重复加载/卸载循环的高耐久性。

Silk-Based Self Powered Pressure Sensor for Applications in Wearable Device

In this work, we demonstrate the development of a flexible self-powered pressure sensor with silk-based substrate. Silk is the thinnest and toughest fiber that can be obtained from nature. Based on these noble properties, its applications for health-care, human-machine interface, and humanoid robotics are highly desired. The synthesized film with silk and poly (vinylidene fluoride-co-trifluoro ethylene) shows piezoelectric coefficient of 6.24pm/V with transmittance up to 88% within visible light range(400~700nm). The obtained sensor shows remarkable linearity with sensitivity of 70Pa−1 in wide range (~500kPa) and high durability over 10,000 times repeated loading/unloading cycles.
