Abstract In vivo bioprinting has recently emerged as a direct fabrication technique to create artificial tissues and medical devices on target sites within the body, enabling advanced clinical strategies. However, existing in methods are often limited applications near skin or require open surgery for printing internal organs. Here, we report ferromagnetic soft catheter robot (FSCR) system capable of situ computer-controlled minimally invasive manner based magnetic actuation. The FSCR is...
Cerebral aneurysms and brain tumors are leading life-threatening diseases worldwide. By deliberately occluding the target lesion to reduce blood supply, embolization has been widely used clinically treat cerebral tumors. Conventional is usually performed by threading a catheter through vessels lesion, which often limited poor steerability of in complex neurovascular networks, especially submillimeter regions. Here, we propose magnetic soft microfiberbots with high steerability, reliable...
Abstract Natural hearing which means naturally like normal people is critical for patients with loss to participate in life. Cochlear implants have enabled numerous severe hear voice functionally, while cochlear implant users can hardly distinguish different tones or appreciate music subject the absence of rate coding and insufficient frequency channels. Here a bioinspired soft elastic metamaterial that reproduces shape key functions human cochlea reported. Inspired by cochlea, metamaterials...
Abstract Multimodal and controllable locomotion in complex terrain is of great importance for practical applications insect‐scale robots. Robust plays a particularly critical role. In this study, mechanism magnetic robots based on asymmetrical friction effect induced by torque revealed defined.

Abstract Untethered miniature soft robots have significant application potentials in biomedical and industrial fields due to their space accessibility safe human interaction. However, the lack of selective forceful actuation is still challenging revolutionizing unleashing versatility. Here, we propose a focused ultrasound-controlled phase transition strategy for achieving millimeter-level spatially Newton-level force robots, which harnesses ultrasound-induced heating trigger inside robot,...
Abstract Bioadhesive hydrogels offer unprecedented opportunities in hemostatic agents and tissue sealing; however, the application of existing bioadhesive through narrow spaces to achieve strong adhesion fluid‐rich physiological environments is challenged either by undesired indiscriminate or weak wet adhesion. Here, a laparoscopically compatible asymmetric adhesive hydrogel (aAH) composed sprayable powders injectable anti‐adhesive glue proposed for hemostasis seal bloody tissues...
Magnetic continuum robots (MCRs) have become popular owing to their inherent advantages of easy miniaturization without requiring complicated transmission structures. The evolution MCRs, from initial designs with one embedded magnet current specific magnetization profile configurations (MPCs), has significantly enhanced dexterity. While much progress been achieved, the quantitative index-based evaluation deformability for different MPCs, which can assist in designing MPCs robot...
Immiscible displacement in porous media is a crucial microscale flow phenomenon many fields, necessitating an understanding of the mechanisms under dynamic injection velocity and mixing wettability to predict affect this accurately. Initially, method computational domain model considering non-dominant/dominant wetting angles were proposed. Then, phenomena modeled pore throat structure doublet geometry mixed conditions. Finally, influence on investigated using numerical simulations. The...
ABSTRACT Minimally invasive transcatheter embolization is a widely utilized in interventional radiology to occlude blood vessels for treating range of diseases and vascular injuries. Various embolic agents, such as metallic coils, microspheres, liquid‐based are delivered the target site effectively block flow achieve vessel occlusion. However, precise selective deployment these agents into lesions remains challenge due limited steerability maneuverability current catheter systems. This...
Water surface jumping motions of semi-aquatic insects are primarily rely on tension-dominated mechanism to achieve impressive performance. However, this faces an inherent physical constraint: the propulsion force must remain below threshold required break water surface, limiting efficient momentum acquisition. Herein, we present a strategy that addresses limitations mechanism. Our approach allows engineered jumper record-breaking height 18 body lengths (63 cm) and take-off velocity 100.6...
Abstract Leveraging the fluidity and excellent conductivity of liquid metal (gallium‐indium alloy), (LM) can be utilized to manufacture flexible stretchable electronic products for applications in soft robotics, wearable devices, human–machine interaction.
