Abstract

Highlights

We propose a broad range triboelectric sensor system employing elastic sponge and shielding layers, which can realize fast stiffness recognition within 1.0 s at a low cost.
A novel algorithm is proposed for rapid stiffness identification by extracting signal characteristics, effectively reducing demand of computing resources.
The proposed sensor system can identify the multi-layer stiffness structure of objects, enabling effective recognition of variable inclusions in soft objects with an accuracy of 99.7%.

一种用于可变夹杂物识别的宽范围摩擦电刚度传感器。

随着人工智能的发展，刚度传感器在各个领域得到了广泛的应用，它们与机器人的集成用于自动触诊也受到了极大的关注。本研究提出了一种基于摩擦电纳米发电机（Stiff TENG）的宽范围自供电刚度传感器，用于软物体检测中的可变夹杂物。Stiff TENG采用堆叠结构，包括氧化铟锡膜、弹性海绵、具有导电油墨电极的氟化乙烯丙烯膜和具有屏蔽层的两个丙烯酸片。通过解耦方法，Stiff TENG在1.0s内实现了对物体的刚度检测。分析了TENG在4mm位移下对不同刚度物体的输出性能和特性。Stiff TENG成功用于检测非均匀刚度结构，能够有效识别软物体中的可变夹杂物，识别准确率达到99.7%。此外，其适应性使其非常适合检测人体内的病理状况，因为病理组织经常表现出内部器官硬度的变化。这项研究突出了TENG的创新应用，从而展示了其在医疗保健应用中的巨大潜力，如根据器官硬度评估病理状况的触诊。

期刊介绍： Nano-Micro Letters is a peer-reviewed, international, interdisciplinary and open-access journal that focus on science, experiments, engineering, technologies and applications of nano- or microscale structure and system in physics, chemistry, biology, material science, pharmacy and their expanding interfaces with at least one dimension ranging from a few sub-nanometers to a few hundreds of micrometers. Especially, emphasize the bottom-up approach in the length scale from nano to micro since the key for nanotechnology to reach industrial applications is to assemble, to modify, and to control nanostructure in micro scale. The aim is to provide a publishing platform crossing the boundaries, from nano to micro, and from science to technologies.
