**Abstract:** The Intelligent and Bio-Mechanical Laboratory at the Department of Mechanical Engineering, Tsinghua University, has achieved a significant breakthrough in the field of triboelectric high-voltage electrostatic adsorption. This innovative technology addresses a major challenge in conventional electrostatic adsorption systems, which require high voltages—often in the range of several thousand volts—to generate sufficient adsorption force, typically supplied by bulky commercial power sources. These systems not only increase costs and complexity but also limit portability and flexibility, hindering further advancements in the technology. In this new approach, the researchers have developed a self-powered electrostatic adsorption system using a Rotational Free-standing Triboelectric Nanogenerator (RF-TENG) to drive a Multi-layer Flexible Film Electrostatic Adsorption Damper (EAD). The system is designed to be lightweight, safe, portable, and easy to operate, marking a significant step forward in the field. The inspiration for this design comes from the natural process of muscle contraction and relaxation. By mimicking this mechanism, the researchers can apply triboelectric high voltage to the conductive electrodes of the electrostatic adsorption film, causing the structure to stiffen in a manner similar to artificial muscles, thus achieving variable stiffness. The self-powered electrostatic adsorption system consists of three main components: the RF-TENG, a rectifier unit, and the EAD. The RF-TENG comprises a stator and a rotor. The stator is a rectangular acrylic plate with two layers of copper foil electrodes covered by a nylon film, while the rotor is a circular acrylic plate with six pie-shaped PVC films. The EAD, on the other hand, is made up of two symmetric parts, each containing the same materials and structure. The comb-like copper foil conductive layers are printed on a polyethylene terephthalate (PET) substrate, followed by a polyimide (PI) dielectric layer. Two identical parts are then combined to form the EAD. A key feature of this technology is the ability to precisely control the equivalent damping coefficient of the EAD by adjusting the driving voltage, which is linearly related to the electrostatic adsorption force. The researchers conducted a detailed analysis of the step and sine responses of a one-dimensional mass-spring-EAD vibration system under various parameters. This analysis revealed that the EAD's equivalent damping coefficient can be accurately and stably controlled between 0.1 N s m-1 and 5 N s m-1, demonstrating the system's versatility and precision. The findings of this study were published in the journal *Advanced Functional Materials* on October 2, 2024, under the title "Thin Film Electrostatic Adsorption Damper Based on Triboelectric High-Voltage." The paper was co-corresponded by Associate Researcher Jia Cheng and Postdoctoral Researcher Ze Yang from the Department of Mechanical Engineering, Tsinghua University, with Zheming Lai, a 2022 master's student in the same department, serving as the first author. The research was supported by the National Natural Science Foundation of China, the National Key Research and Development Program, and the National Laboratory for Interface Science and Technology of Advanced Manufacturing at Tsinghua University. This development not only enhances the practicality and efficiency of electrostatic adsorption systems but also opens new avenues for the application of triboelectric nanogenerators in high-voltage scenarios. The potential applications of this technology are wide-ranging, including but not limited to semiconductor manufacturing, robotics, and flexible grippers. The self-powered nature of the system and its ability to provide precise control over electrostatic adsorption characteristics make it a promising candidate for future innovations in these fields.
