High-performance flexible strain sensors with a low cost, simple structure, and large-scale fabrication methods have a high demand in soft robotics, wearable devices, and health monitoring. Here, a direct-ink-writing-based 3D printing method, which fabricates structural layers in an efficient, layered manner, was developed to fabricate a stretchable and flexible strain sensor composed of carbon black/silicone elastomer (CB/PDMS) composites as the strain-sensing elements and electrodes. As the sensing element, the CB/PDMS composite had a sensitivity of 5.696 in the linear strain detection range of 0 to 60%, with good stability and low hysteresis. The flexible strain sensor demonstrates potential in monitoring various human motions, including large deformation motions of the human body, and muscle motions with facial micro-expressions.
具有低成本、结构简单和大规模制造方法的高性能柔性应变传感器在软机器人技术、可穿戴设备和健康监测领域有很高的需求。在此，开发了一种基于直接墨水书写的3D打印方法，该方法以高效的分层方式制造结构层，以制造一种由炭黑/硅橡胶（CB/PDMS）复合材料作为应变传感元件和电极的可拉伸且柔性的应变传感器。作为传感元件，CB/PDMS复合材料在0至60%的线性应变检测范围内灵敏度为5.696，具有良好的稳定性和低滞后性。这种柔性应变传感器在监测各种人体运动方面展现出潜力，包括人体的大变形运动以及伴有面部微表情的肌肉运动。
