Flexible on-skin electronics present tremendous popularity in intelligent electronic skins (e-skins), healthcare monitoring, and human-machine interfaces. However, the reported e-skins can hardly provide high permeability, good stretchability, and large sensitivity and are limited in long-term stability and efficient recyclability when worn on the human body. Herein, inspired from the human skin, a permeable, stretchable, and recyclable cellulose aerogel-based electronic system is developed by sandwiching a screen-printed silver sensing layer between a biocompatible CNF/HPC/PVA (cellulose nanofiber/hydroxypropyl cellulose/poly(vinyl alcohol)) aerogel hypodermis layer and a permeable polyurethane layer as the epidermis layer.

Cartilage tissue engineering presents a promising therapeutic avenue, but success hinges on replicating the native physiological environment to guide cellular behavior and generate tissue constructs that mimic natural cartilage. Although electrical stimulation has been shown to enhance chondrogenesis and extracellular matrix production in 2D cultures, the mechanisms underlying these effects remain poorly understood, particularly in 3D models.

In the past decade, 4D printing has received attention in the aerospace, automotive, robotics, and biomedical fields due to its lightweight structure and high productivity. Combining stimulus-responsive materials with 3D printing technology, which enables controllable changes in shape and mechanical properties, is a new technology for building smart bearing structures. A multilayer smart truss structural component with self-sensing function is designed, and an internal stress calibration strategy is established to better adapt to asymmetric loads.

The fabrication of 3D bioconstructs using bioprinters will advance the field of regenerative medicine owing to its ability to facilitate clinical treatments. Additional stimulations have been applied to the bioconstructs to guide cells laden in the bioconstructs. However, the conventional bench-to-bedside delivery based on separate bioprinting and biostimulating processes may increase the risks of contamination and shape discordance owing to the considerably long process involved.

The previously reported hydrogel assemblies carry bulky shapes, for which the unitary assembly form immensely restricted further applications. Yet there are abundant natural examples of network-shaped assemblies constructed by animals, of which it is brought up inspirations for constructing hydrogel assemblies. Herein, the network-shaped assemblies with diverse functions are reported.
