“…Scholars investigated various biomaterials-based hydrogels with high adhesion, , repeatable adhesion (Figure A), − and the ability to adhere to a variety of matrix (wood, glass, metal, plastic, rubber, biological tissue, etc. ). ,, Meanwhile, since hydrogels with isotropic adhesion may not perform well in practice (e.g., adhering to foreign objects, impairing sensing stability), scholars have investigated hydrogels with asymmetric (anisotropic) adhesion (no adhesion on the upper surface and adhesion maintained on the lower surface in contact with human skin), while wet adhesion has also received much attention recently.…”

As noninvasive wearable electronic devices, epidermal sensors enable continuous, real-time, and remote monitoring of various human physiological parameters. Conductive biomaterials-based hydrogels as sensor matrix materials have good biocompatibility, biodegradability, and efficient stimulus response capabilities and are widely applied in motion monitoring, healthcare, and human−machine interaction. However, biomass hydrogelbased epidermal sensing devices still need excellent mechanical properties, prolonged stability, multifunctionality, and extensive practicality. Therefore, this paper reviews the common biomass hydrogel materials for epidermal sensing (proteins, polysaccharides, polyphenols, etc.) and the various types of noninvasive sensing devices (strain/pressure sensors, temperature sensors, glucose sensors, electrocardiograms, etc.). Moreover, this review focuses on the strategies of scholars to enhance sensor properties, such as strength, conductivity, stability, adhesion, and self-healing ability. This work will guide the preparation and optimization of high-performance biomaterials-based hydrogel epidermal sensors.

“…Currently, the commonly used method to enhance the adhesion of PAA hydrogels is to introduce organic polymers with high viscosity. For example, Chao et al 22 prepared a composite hydrogel with excellent adhesion by combining tannic acid coated cellulose nanocrystals with pectin and PAA. The abundant catechol groups in the prepared hydrogels enable the composite hydrogels to adhere to various hydrophilic and hydrophobic substrates.…”

A bio‐hydrogel is prepared via a low‐cost and time‐saving strategy and is studied as a self‐powered wound dressing for precision medicine and health monitoring. Promoted by a dual self‐catalytic pair composed of Fe3+ and catechol, gelation time is dramatically accelerated to 15 s and the hydrogel can be freely modeled at −18 °C without losing flexibility. As smart wound dressing, the required properties such as self‐healing, self‐adhesion, antibacterial, and sensing stability, are integrated into one hydrogel. TA@CNC offers abundant hydrogen bond and metal‐ligand coordination which facilitate the hydrogel with a self‐healing efficiency of 91.6%. Owing to the catechol in TA@CNC, hydrogel can adhere to multiple substrates including skin, and show good antibacterial activity. Inspired by a fruit battery, a self‐powered wound dressing is fabricated, which exhibits excellent correlation and efficiency in real‐time monitoring of body activity and drug release. In vivo experiments prove that efficient drug release of hydrogel dressing significantly accelerate wound healing. Additionally, the dressing exhibits excellent biocompatibility and has no negative impacts on organs. Herein, a smart wound dressing that is different from the traditional way is proposed. As a self‐powered device, it can be integrated with wireless devices and is expected to participate in promising applications.
