Triboelectric nanogenerators (TENGs) are highly promising because they can scavenge energy from their working environment to sustainably power wearable/mobile electronics. In this work, we propose a novel and straightforward strategy for six-axis force detection and object controlling by using a self-powered sensor based on TENG. The self-powered sensor can be used in diversified tactile sensing and energy saving applications, which has been demonstrated to be able to detect normal force in the range of 0⁻18 N. Using the vector properties of external force, six-axis directions in three-dimensional (3D) space is detected. Additionally, it is fabricated with environmental friendly materials, i.e., galinstan and polydimethylsiloxane (PDMS), promoting its applications in more diversified situations. Because of the available and high output voltage as well as the low internal impedance, the self-powered sensor is readily compatible with commercial signal processing and management circuits. The device presented in this work shows robust structure and stable output performance, enabling itself as an ideal human machine interface in self-powered, batteryless, and electric energy saving applications.
摩擦纳米发电机（TENGs）极具前景，因为它们能够从工作环境中收集能量，为可穿戴/移动电子产品可持续供电。在这项工作中，我们提出了一种新颖且直接的策略，通过使用基于TENG的自供电传感器进行六轴力检测和物体控制。该自供电传感器可用于多种触觉传感和节能应用，已证明能够检测0至18 N范围内的法向力。利用外力的矢量特性，可检测三维（3D）空间中的六轴方向。此外，它由环保材料制成，即镓铟锡合金和聚二甲基硅氧烷（PDMS），这促进了其在更多样化场景中的应用。由于具有可用的高输出电压以及低内阻，该自供电传感器很容易与商业信号处理和管理电路兼容。这项工作中展示的器件结构坚固，输出性能稳定，使其成为自供电、无电池和节能应用中理想的人机接口。
