Abstract Nature provides much inspiration for developing soft millirobots. However, compared with smart and adaptations of lives in nature, these robotic systems still suffer from insufficiency intelligence. Here, a new untethered millirobot magnetic actuation the head function tail is presented via implementing control, actuation, sensing directly materials, thereby endowing robots multimodal locomotion environment‐adaptive functions. Due to asymmetric structure, not only shows robust...
Abstract Rapid formation of a confluent endothelial monolayer is the key to success small‐diameter vascular grafts, which significantly important for treating dangerous and even sometimes deadly disorders. However, difficulty homogenously locate cells onto lumen tubular scaffolds makes 3D endothelialization greatly challenging. Here, novel shape‐morphing enabling programmed deformation from planar shapes are designed developed by combining biocompatible shape memory polymer electrospun...

Abstract Effective contact between flexible electronics and soft biological tissues, which may have different surface curvatures, for medical applications has long been a challenge. Here, this study reports strategy preparing shape‐adaptable 3D by combining photothermally responsive poly( N ‐isopropylacrylamide)/gold nanorods (PNIPAM@AuNRs) composite hydrogels with conventional microelectrode arrays (fMEAs). The fMEAs‐functionalized are can accommodate geometries. Triggered remotely in...
Shape morphing is a critical aptitude for the survival of organisms and determined by anisotropic tissue composition directional orientation micro- nanostructures within cell walls, resulting in different swelling behaviors. Recent efforts have been dedicated to mimicking behaviors that nature has perfected over billions years.

The formation of complete and well-functioning endothelium is critical for the success tissue-engineered vascular grafts yet remaining a fundamental challenge. Endothelium remodeling onto lumen affected by their topographical, mechanical, biochemical characteristics. For meeting multiple requirements, composite strategies have recently emerged fabricating hybrid scaffolds, where integrated properties are tuned varying compositions. However, underlying principle how scaffolds regulate remains...
Endothelialization is of great significance for vascular remodeling, as well the success implanted grafts/stents in cardiovascular disease treatment. However, desirable endothelialization on synthetic biomaterials remains greatly challenging owing to extreme difficulty offering dynamic guidance endothelial cell (EC) functions resembling native extracellular matrix-mediated effects.
