保形可伸缩输入器件技术的发展对各种可穿戴电子产品的发展具有重要意义。在此，我们报告了一种电容式触摸传感器，通过使用石墨烯和薄器件几何结构，在接触和非接触模式下都具有良好的传感能力。这种装置可以与人体高度变形的部位集成，比如前臂和手掌。这种触摸传感器在急性记录中检测多个触摸信号，并在直接接触之前识别接近物体的距离和形状。这项技术提供了一个方便和身临其境的人机界面和额外的潜在用途，作为新兴的可穿戴电子和机器人的多功能传感器。
The development of input device technology in a conformal and stretchable format is important for the advancement of various wearable electronics. Herein, we report a capacitive touch sensor with good sensing capabilities in both contact and noncontact modes, enabled by the use of graphene and a thin device geometry. This device can be integrated with highly deformable areas of the human body, such as the forearms and palms. This touch sensor detects multiple touch signals in acute recordings and recognizes the distance and shape of the approaching objects before direct contact is made. This technology offers a convenient and immersive human machine interface and additional potential utility as a multifunctional sensor for emerging wearable electronics and robotics.
