摘　　要：The manufacture of 3D mesostructures is receiving rapidly increasing attention,because of the fundamental significance and practical applications across wide-ranging areas.The recently developed approach of buckling-guided assembly allows deterministic formation of complex 3D mesostructures in a broad set of functional materials;with feature sizes spanning nanoscale to centimeter-scale.Previous studies mostly exploited mechanically controlled assembly platforms using elastomer substrates;which limits the capabilities to achieve on-demand local assembly;and to reshape assembled mesostructures into distinct 3D configurations.This work introduces a set of design concepts and assembly strategies to utilize dielectric elastomer actuators as powerful platforms for the electro-mechanically controlled 3D assembly.Capabilities of sequential-local loading with desired strain distributions allow access to precisely tailored 3D mesostructures that can be reshaped into distinct geometries,as demonstrated by experimental and theoretical studies of?30 examples.A reconfigurable inductive-capacitive radio-frequency circuit consisting of morphable 3D capacitors serves as an application example.
