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, large sensitivity are limited long-term stability efficient recyclability when worn on human body. Herein, inspired from skin, a permeable, stretchable, recyclable cellulose aerogel-based system is developed by sandwiching screen-printed silver sensing layer between biocompatible CNF/HPC/PVA (cellulose nanofiber/hydroxypropyl cellulose/poly(vinyl alcohol)) aerogel hypodermis permeable polyurethane as epidermis layer. The displays tensile strength of 1.14 MPa strain 43.5% while maintaining permeability. embrace appealing performances with (gauge factor ≈ 238), ultralow detection limit (0.1%), fast response time (18 ms) under stimulus. Owing to disconnection reconnection microcracks layer, both strain/humidity thermal be easily achieved. further integrated into an mask for patient-centered power supply system, switching control device, wireless Bluetooth module. Moreover, prepared enables wearing skin without irritation, all components recaptured/reused water. This material strategy highlights potential next-generation permeability environmental friendliness.

The current wearable devices are largely rigid and bulky, which calls for the development of next-generation soft biocompatible technologies. Another limitation is that conventional generally powered by thick non-compliant batteries, hindering miniaturization improvement electronics. Hydrogels have attracted tremendous attention in field bioelectronics due to their tissue-like properties, can minimize mechanical mismatch between flexible biological tissues. Moreover, take advantage physical chemical energy from human body or ambient environment, such as motions, heat energy, biofuel, water wind power nature, more novel technology portable supply has been carried out, facilitating bioelectronics. In this review, recent advances self-powered based on hydrogels summarized. Firstly, excellent properties introduced, including prominent self-healing high conductivity incorporation conductive polymers additives, interfacial adhesion functionality, biocompatibility, antibacterial properties. Then, several strategies harvesting discussed, triboelectric nanogenerators (TENGs), piezoelectric (PENGs), thermoelectric (TEGs), biofuel cells (BFCs), hydrovoltaics, antennas, hydrogel-based batteries. Next, some representative applications illustrated (i.e., motion monitoring, healthcare monitoring therapies, neural stimulation human-machine interaction). Finally, a brief summary outlook hydrogel presented.

Stimulus-responsive hydrogels can undergo controllable shape deformation and exhibit sol-gel transition behavior under stimulus signals such as pH, reactive oxygen species (ROS), heat, light. Polysaccharides have become ideal candidates for constructing stimulus-responsive due to their biocompatibility biodegradability. The diversity of molecular weights functional groups polysaccharides allows them self-assemble or cooperate with other materials obtain through physical chemical crosslinking. Bioactive ingredients nanomaterials be conveniently encapsulated in the hydrogel matrix meet various requirements. polysaccharide-based are widely used biomedical field, especially fields drug delivery, tissue engineering, biosensors, imaging. In this review, design strategies recent research advances stimuli-responsive summarized. Future challenges also presented, review will guide study polysaccharide hydrogels.

Abstract Conductive hydrogels (CHs) are attracted more attention in the flexible wearable sensors field, however, how to stably apply CHs underwater is still a big challenge. In order achieve usage of aquatic environments, integrated properties such as water retention ability, resistance swelling, toughness, adhesiveness, linear GF sensing, and long‐term necessary consider, but rarely reported previous reports. This paper proposes prepared using cationic aromatic monomers along with polyrotaxanes‐based crosslinkers. Due intermolecular cation‐π interactions topological slide‐ring‐based polyrotaxanes, exhibit good mechanical performance, adhesive nature, anti‐swelling properties. The presence architecture effectively mitigates stress concentration. Additionally, encapsulation PA allows maintain functionality even after 240 days direct placement at room temperature. Notably, designed sensitivity detecting land/underwater human motions, serve Morse code signal transmitters for information transmission. Thus, may have broad applications field.
