Human-machine interface plays an extremely important role in the diversified interactions between humans and machines especially in the era of the internet of things (IoT), by enabling information exchange between human and machine operations. Considering the high wearable compatibility and self-powered capability, triboelectric based interfaces have attracted increasing attention. However, most of them have the disadvantages of complex structures, large number of sensing elements/electrodes, and limited detection capability of the applied multi-parameter interaction. Herein, we present a minimalist and self-powered interacting patch based on the complementary integration of the triboelectric and piezoelectric sensing mechanism, achieving the simultaneous detection of multi-parameter sensory information of finger operations, i.e., contact position, sliding trace, and applied pressure. The 2D position and trace information in the x–y plane is detected by the triboelectric unit with only four electrodes, while the contact force (z-direction information) is detected by the integrated piezoelectric unit. Benefited by this multi-parameter sensing capability, the interacting patch is successfully demonstrated as a writing pad, a 2D virtual car control, and a 3D virtual drone control interface, indicating its high adaptability in various human-machine interactions. Moreover, the proposed interacting patch is also verified with good performance in scavenging energy from human tapping. These results imply that the minimalist and self-powered interacting patch possesses high applicability and immediate practicality in various human-machine interactions, e.g., energy harvesting, writing pad, auto-control, robotics, virtual reality, augmented reality, and wearable electronics, etc.

人机界面通过实现人机操作之间的信息交换，在人机之间的多样化交互中发挥着极其重要的作用，尤其是在物联网（IoT）时代。考虑到高可穿戴兼容性和自供电能力，基于摩擦电的接口已引起越来越多的关注。然而，它们中的大多数具有结构复杂，感测元件/电极数量大以及所施加的多参数相互作用的检测能力有限的缺点。本文中，我们基于摩擦电和压电传感机制的互补集成，提出了一种极简且自供电的互动式贴片，可同时检测手指操作的多参数感官信息，即接触位置，滑动轨迹，并施加压力。x-y平面中的2D位置和轨迹信息由只有四个电极的摩擦电单元检测，而接触力（z方向信息）则由集成压电单元检测。得益于此多参数感测功能，交互补丁已成功演示为书写板，2D虚拟汽车控件和3D虚拟无人机控制界面，表明其在各种人机交互中的高度适应性。此外，所提出的相互作用的贴剂在清除人为敲击的能量方面也具有良好的性能。这些结果表明，极简且自供电的交互补丁在各种人机交互（例如能量收集，书写板，
