•The adhesive utilizes an electro-responsive polymer composite that undergoes a reversible phase transition when subjected to a low-voltage electrical current.
•Researchers at Northwestern Polytechnical University (NPU) integrated conductive nanomaterials into the polymer matrix to facilitate rapid electron transport and adhesion switching.
•The material demonstrates high fatigue resistance, maintaining its 400x adhesion enhancement capability over thousands of activation cycles without significant degradation.
•The activation mechanism is based on electrostatic attraction combined with surface energy modulation, allowing for 'instant' release when the power is cut.
•The material is designed to be solvent-free and environmentally stable, addressing common limitations of traditional industrial adhesives in cleanroom environments.

Mechanism: Employs an electro-rheological or electro-adhesion principle where the application of an electric field induces polarization in the material interface.
Response Time: The transition from low-adhesion to high-adhesion state occurs in milliseconds, enabling high-speed industrial automation.
Power Requirements: Operates on low-voltage DC power, making it compatible with standard micro-controller and robotic control systems.
Material Composition: Incorporates a proprietary blend of conductive fillers within a thermoplastic elastomer matrix to balance flexibility and structural integrity.
Load Capacity: The 400x multiplier is achieved through a thin-film interface, specifically optimized for shear stress resistance in vertical lifting applications.
