Abstract

Combination flexible and stretchable textiles with self-powered sensors bring a novel insight into wearable functional electronics and cyber security in the era of Internet of Things. This work presents a highly flexible and self-powered fully fabric-based triboelectric nanogenerator (F-TENG) with sandwiched structure for biomechanical energy harvesting and real-time biometric authentication. The prepared F-TENG can power a digital watch by low-frequency motion and respond to the pressure change by the fall of leaves. A self-powered wearable keyboard (SPWK) is also fabricated by integrating large-area F-TENG sensor arrays, which not only can trace and record electrophysiological signals, but also can identify individuals' typing characteristics by means of the Haar wavelet. Based on these merits, the SPWK has promising applications in the realm of wearable electronics, self-powered sensors, cyber security, and artificial intelligences.

摘要

将柔性可拉伸纺织品与自供电传感器相结合，为物联网时代的可穿戴功能电子学和网络安全带来了新的见解。这项工作展示了一种具有夹层结构的高度柔性且自供电的全织物摩擦纳米发电机（F-TENG），用于生物机械能收集和实时生物特征认证。制备的F-TENG可以通过低频运动为电子手表供电，并能对树叶掉落产生的压力变化做出响应。通过集成大面积F-TENG传感器阵列还制造了一种自供电可穿戴键盘（SPWK），它不仅可以跟踪和记录电生理信号，还可以借助哈尔小波识别个体的打字特征。基于这些优点，SPWK在可穿戴电子学、自供电传感器、网络安全和人工智能领域具有广阔的应用前景。
