外文摘要：Small-scale robots,ranging in size from micrometers to centimeters,have gained significant attention in the biomedical field.However,conventional small-scale robots made of rigid materials encounter challenges in adapting themselves to the soft tissues and complicated environments of human body.Compared to the rigid counterpart,small-scale hydrogel-based robots hold great promises due to their tissue-like low modulus,outstanding biocompatibility and accessible stimuli-responsive capabilities.These attributes offer small-scale hydrogel-based robots with multimodal locomotion and reinforced functions,further enhancing the adaptability in manipulation and tasks execution for various biomedical applications.In this review,we present recent advances in small-scale hydrogel-based robots.We first summarize the design principles of small-scale hydrogel-based robots including materials,fabrication techniques and manipulation strategies,then highlighting their upgraded functions and adaptive biomedical applications.Finally,we discuss existing challenges and future perspectives for small-scale hydrogel-based robots.
