Exploiting novel devices for either collecting energy or self‐powered sensors is vital for Internet of Things, sensor networks, and big data. Triboelectric nanogenerators (TENGs) have been proved as an effective solution for both energy harvesting and self‐powered sensing. The traditional triboelectric nanogenerators are usually based on four modes: contact‐separation mode, lateral sliding mode, single‐electrode mode, and freestanding triboelectric‐layer mode. Since the reciprocating displacement/force is necessary for all working modes, developing efficient elastic TENG is going to be important and urgent. Here, a kind of elastic‐beam TENG with arc‐stainless steel foil is developed, whose structure is quite simple, and its working states depend on the contact area and separating distance as proved by experiments and theoretical calculations. This structure is different from traditional structures, e.g., direct sliding or contact‐separation structures, whose working states mainly depend on contact area or separating distance. This triboelectric nanogenerator shows advanced mechanical and electrical performance, such as high sensitivity, elasticity, and ultrahigh frequency response, which encourage applications as a force sensor, sensitivity scale, acceleration sensor, vibration sensor, and intelligent keyboard.

弹性束摩擦纳米发电机，用于高性能多功能应用：灵敏秤，加速度/力/振动传感器和智能键盘

开发用于收集能量或自供电传感器的新颖设备对于物联网，传感器网络和大数据至关重要。摩擦电纳米发电机（TENGs）已被证明是一种用于能量收集和自供电传感的有效解决方案。传统的摩擦电纳米发电机通常基于四种模式：接触分离模式，横向滑动模式，单电极模式和独立式摩擦电层模式。由于往复位移/力对于所有工作模式都是必需的，因此开发有效的弹性TENG将变得重要而紧迫。在这里，开发了一种带有电弧不锈钢箔的弹性梁TENG，其结构非常简单，并且其工作状态取决于接触面积和分离距离，这是通过实验和理论计算证明的。这种结构不同于传统的结构，例如直接滑动或接触分离结构，其工作状态主要取决于接触面积或分离距离。这种摩擦电纳米发电机具有先进的机械和电气性能，例如高灵敏度，弹性和超高频响应，因此鼓励将其用作力传感器，灵敏度标尺，加速度传感器，振动传感器和智能键盘。
