Developing flexible and sustainable power sources for multifunctional and self-powered sensors is crucial for electronic skin. Herein, we report a versatile, ultraflexible, high sensitivity, fish bladder film-based triboelectric nanogenerator (FBF-TENG) for smart electronic skin. A salient feature of the FBF-TENG is that a natural material acts as a triboelectric layer, which has good biocompatibility and degradability. The FBF-TENG exhibits good electrical performance for collecting biological energy, with output current density and charge density of nearly 4.56 mA/m² and 25 μC/m², respectively. In addition, the FBF-TENG-based electronic skin can respond linearly to acceleration and humidity with good sensitivity of about 446 nA·s²/m and 50 nA/% RH. Interestingly, the as-prepared FBF-TENG-based electronic skin also presents sensing performance of noncontact position in the range of 0–27 mm. These multifunctional advantages make it ideal for many applications, including human–machine interfacing, intelligent interfaces, and prosthetics.

基于鱼囊膜的摩擦电纳米发电机非接触式位置监测

为多功能和自供电传感器开发灵活，可持续的电源对于电子皮肤至关重要。在此，我们报告了一种用于智能电子皮肤的多功能，超柔韧性，高灵敏度，基于鱼囊膜的摩擦纳米发电机（FBF-TENG）。FBF-TENG的一个显着特征是天然材料充当摩擦电层，具有良好的生物相容性和可降解性。FBF-TENG具有良好的电气性能，可收集生物能量，其输出电流密度和电荷密度分别接近4.56 mA / m ²和25μC/ m ²。此外，基于FBF-TENG的电子皮肤可以对加速度和湿度做出线性响应，灵敏度约为446 nA·s ²/ m和50 nA /％RH。有趣的是，所准备的基于FBF-TENG的电子皮肤还具有0-27 mm范围内非接触位置的感应性能。这些多功能的优势使其非常适合许多应用，包括人机界面，智能接口和修复工具。
