“…It is widely acknowledged that when wheat dough being teared, dough fragments can be rolled up and kneaded, thus making a reshaped dough without obvious performance degradation 11 . The principle behind it is the dynamic construction of and conversion between S-S bonds and free -SH groups together with the assistance of intramolecular and intermolecular H-bonds involved in the gluten network rebuilding process.…”

“…Upon hydration and kneading, gluten is known to form a cross-linked three-dimensional protein polymeric network through intra-and inter-molecular covalent and noncovalent bonds. The gluten network possesses various dynamic bonds, like dynamic covalent disul de (S-S) bonds and noncovalent H-bonds, thus guaranteeing the self-healing ability that most SF-based e-skin loses 1,[9][10][11][12] . Generally, for eskin preparation, the macroscopic mechanical performances of synthetic materials, like supramolecular polymers, can be adjusted by constructing cross-linking positions inside the microscopic network structure [13][14][15] .…”

Designing electronic skin (e-skin) with proteins is a critical way to endow e-skin with biocompatibility, but engineering protein structures to achieve controllable mechanical properties and self-healing ability remains a challenge. Here, we develop a hybrid gluten network through the incorporation of an eutectic gallium indium alloy (EGaIn) to design a self-healable e-skin with improved mechanical properties. The intrinsic reversible disulfide bonds/sulfhydryl groups reconfiguration of gluten networks is explored as a driving mechanism to introduce EGaIn as chemical cross-linkers to create hierarchical sulphur bonds, thus inducing the secondary structure rearrangement of gluten to form additional β-sheets as physical cross-linkers. Remarkably, this strategy allows the gluten network to realize a synthetic material-like stretchability (>1600%) and to endure a three-dimensional strain change. The obtained e-skin is biocompatible and biodegradable, and can sense strain changes from different scale human motions. The protein network micro-regulation method paves the way for future skin-like protein-based e-skin.

“…Therefore, physically cross-linked hydrogels with self-healability and flexibility that can adapt to dynamic surfaces have been recently developed. However, these systems showed poor structural integrity, insufficient anti-fatigue properties, and plastic deformation under external force, which can compromise the materials stability and functionality of the ionic skins[ 8 - 11 ]. Therefore, it is still a challenge to develop hydrogel-based electronic sensors as ionic skins that feature the combined attributes of adaptability, high elasticity, and stretchability.…”

A hydrogel that combines both printability and adaptability, high elasticity, and stretchability can provide ideal mechanical properties, and also render complex and accurate construction for ionic skin. However, it is extremely challenging. Here, we propose a colloidal-based double-network (DN) hydrogel as printable inks for high-precision fabrication of ionic skins. Particularly, polyacrylamide (PAAm), as the covalent network that can maintain the long-term material integrity, was combined with gelatin colloidal network to improve the injectability and printability of the resulting DN hydrogels. The DN design cooperatively provides the hydrogels with higher toughness values and deformability than what single colloidal or PAAm network can achieve. Further design of ionic skin based on capacitor microarray was demonstrated to serve as a sensitive and stable capacitor that can respond to external stimuli, thereby allowing to sense the body movements such as finger bending, laugh, and wrist pulse by translating mechanical changes into electric signals. Therefore, this study provides a novel strategy for the design and preparation of high-resolution ionic skins as the wearable sensor.

Passive radiative technology enables sustainable cooling by synchronously emitting heat and reflecting solar light without any energy consumption. However, the consumption of non-recyclable and non-renewable radiative materials in large quantities may eventually cause resource waste and environmental issues. Herein, reconfigurable and renewable nano-micro-structured plastics for future eco-friendly and large-scale radiative cooling applications are developed. The plastics are facilely prepared from a locally confined polymerization method, which not only enables the customization of nano/micro-structures for thermal emission and sunlight reflection but also provides physically crosslinked networks for damage repairing, shape reconfiguration, and recyclable usage. Compared with traditional plastics applied on electronic devices, the nano-micro-structured plastic achieves much higher cooling efficiency with a temperature drop of 8.6 °C on electronic circuits and 7.5 °C cooling improvements under sunlight. With the excellent cooling performance and the recycling potential, the nano-micro-structured plastics open an environmentally sustainable pathway to address the thermal issues encountered by electronic devices and challenges of global warming.
