Electroadhesion generates an adhesion force using an externally applied power source, which has versatile applications in robotics and material handling. In this study, a self-powered electroadhesion system using enhanced triboelectric nanogenerators (TENGs) to supply power for electroadhesion is presented. By introducing a triboelectric charge supplement channel, the open circuit voltage of the TENG can be significantly boosted by over 10 times, from ∼230 V to more than 3300 V for a single TENG unit, providing sufficiently high voltage for an electroadhesive patch to generate enough adhesion for practical use. The charge supplement channel takes effect through a replenishing mechanism for dissipated charges, maintaining an optimal charge distribution throughout TENG electrodes, which enables the highest open circuit voltage under given surface charge density and device configuration. The fabricated self-powered electroadhesion system shows the ability to manipulate objects of various materials via easy and straightforward operations, demonstrating a great potential for applications in material handling and robotics. Moreover, the voltage enhancement mechanism by the charge supplement channel could be extended to TENGs of other modes, which can provide reliable power sources for various applications that require a high voltage.

通过摩擦电荷补充通道的巨大电压增强，可实现自供电电粘附

电粘附力使用外部施加的电源产生粘附力，该动力源在机器人技术和材料处理中具有广泛的应用。在这项研究中，提出了一种使用增强型摩擦电纳米发电机（TENGs）为电粘附提供动力的自供电电粘附系统。通过引入摩擦电荷补充通道，单个TENG单元可将TENG的开路电压从大约230 V显着提高10倍以上，从约230 V增至3300 V以上，从而为电胶贴片提供足够高的电压以产生足够的电压实际使用中的附着力。电荷补充通道通过补充机制来实现消散电荷，从而在整个TENG电极上保持最佳电荷分布，在给定的表面电荷密度和器件配置下，它可以实现最高的开路电压。预制的自供电电粘附系统显示了操纵各种材料的能力通过简单明了的操作，证明了在物料搬运和机器人技术方面的巨大潜力。此外，通过电荷补充通道的电压增强机制可以扩展到其他模式的TENG，从而可以为需要高压的各种应用提供可靠的电源。
