The design of bioinspired dry adhesives mimicking closely the structure and surface adaptability of biological adhesives is challenging. Here, the authors propose an electrically responsive self-growing core–shell mushroom-shaped structure with a rigid core and a soft shell, which exhibits excellent adhesion on surfaces with roughness ranging from the nanoscale to the microscale.
