Abstract As an on‐skin electronic device, artificial skin shows great potential in medical monitoring and personal electronics, which also holds promise to develop human‐machine merging interfaces. However, skins with human bodies is largely restricted by the dissimilarity of material compositions existing biological tissues. Naturally conductive protein a candidate for skins, nevertheless, it suffers from critical issue dehydration harms its proton conductivity. Inspired sebum membrane skin, herein, protein‐based bioprotonic hydrogel (PBH) reliable water retention ability reported skins. The bovine serum albumin natural conductivity utilized PBH, glycerol that originally presents on surface used as retain water. PBH can act (B‐skin) collecting electrophysiological signals self‐powered sensing. Based B‐skin, intelligent robot cellphone control systems are demonstrated. Compared present this B‐skin all made out materials consistent components tissues including proteins, endogenous glycerol, Such may enable development next‐generation

As water-saturated polymer networks, hydrogels are a growing family of soft materials that have recently become promising candidates for flexible electronics application. However, it remains still difficult hydrogel-based strain sensors to achieve the organic unity mechanical properties, electrical conductivity, and water retention. To address this challenge, based on template, excellent properties MXene nanoflakes (rich surface functional groups, high specific area, hydrophilicity, conductivity) fully utilized in study prepare P(AA-co-AM)/MXene@PDADMAC semi-interpenetrating network (semi-IPN) hydrogel. The proposed hydrogel continues exhibit response flexibility after 30 days storage at room temperature, its performance do not decrease 1100 cycles. Considering these characteristics, device converting sign language into Chinese characters is successfully developed optimized using machine learning. Therefore, provides novel insight application directions families.

Abstract Due to their intrinsic flexibility, tunable conductivity, multiple stimulus‐response, and self‐healing ability, ionic conductive hydrogels have drawn significant attention in flexible/wearable electronics. However, challenges remain because traditional inevitably faced the problems of losing flexibility conductivity inner water loss when exposed ambient environment. Besides, inside hydrogel will freeze at icing temperatures, making device hard fragile. As a promising alternative, organogels attracted wide they can, some extent, overcome above drawbacks. Herein, kind organogel conductor (MOIC) by self‐polymerization reaction is involved, which super stretchable, anti‐drying, anti‐freezing. Meanwhile, it can still maintain high mechanical stability after alternately loading/unloading strain 600% for 600 s (1800 cycles). Using this MOIC, high‐performance triboelectric nanogenerator (TENG) constructed (MOIC‐TENG) harvest small energy even MOIC electrode underwent an extremely low temperature. In addition, multifunctional sensors (strain sensor, piezoresistive tactile sensor) are realized monitor human motions real time, recognize different materials effect. This study demonstrates candidate material electronics such as electronic skin, flexible sensors, human‐machine interfaces.
