Abstract Tissue adhesives are promising alternatives to sutures and staples for joining tissues, sealing defects, immobilizing devices. However, existing mostly take the forms of glues or hydrogels, which offer limited versatility. We report a direct-ink-write 3D printable tissue adhesive can be used fabricate bioadhesive patches devices with programmable architectures, unlocking new potential application-specific designs. The is conformable stretchable, achieves robust adhesion wet tissues...
Metal-organic frameworks (MOFs) are promising materials for gas sensing but often limited to single-use detection. A hybridization strategy is demonstrated synergistically deploying conductive MOFs (cMOFs) and polymers (cPs) as two complementary mixed ionic-electronic conductors in high-performing stand-alone chemiresistors. This work presents significant improvement i) sensor recovery kinetics, ii) cycling stability, iii) dynamic range at room temperature. The effect of across well-studied...
Abstract Owing to low‐power, fast and highly adaptive operability, as well scalability, electrochemical random‐access memory (ECRAM) technology is one of the most promising approaches for neuromorphic computing based on artificial neural networks. Despite recent advances, practical implementation ECRAMs remains challenging due several limitations including high write noise, asymmetric weight updates, insufficient dynamic ranges. Here, inspired by similarities in structural functional...
Perfluoroalkyls (PFAS) continue to emerge as a global health threat making their effective detection and capture extremely important. Though metal-organic frameworks (MOFs) have stood out promising class of porous materials for sensing PFAS, limits remain insufficient fundamental understanding mechanisms warrants further investigation.

Iono-electronics, that is, transducing devices able to translate ionic injection into electrical output, continue demand a variety of mixed ionic-electronic conductors (MIECs). Though polar sidechains are widely used in designing novel polymer MIECs, it remains unclear chemists how much balance is needed between the two antagonistic modes transport (ion permeability and electronic charge transport) yield high-performance materials. Here, impact molecularly hybridizing ion mobility...
Abstract It has been over four decades since organic semiconducting materials were said to revolutionize the way we interact with electronics. As many had started argue that semiconductors are a dying field of research, have recently seen rebirth and major push towards adaptive on-body computing using materials. Whether assisted by publicity neuroprosthetics through technological giants (e.g., Elon Musk) or sparked software capabilities handle larger datasets than before, witnessing surge in...
Stretchable electrode is an essential part of soft electronic devices. Practical stretchable electrodes must meet the following requirements: metallic conductivity and no resistance change in various situations such as repeated large deformation, toxic environment, temperature change. This study suggests a simple design that meets all these requirements simultaneously. The consists liquid metal (LM) mesh pattern sandwiched between thermoplastic block copolymer (BCP) film BCP/Ag flake...
Abstract Owing to the unique combination of electrical conductivity and tissue-like mechanical properties, conducting polymer hydrogels have emerged as a promising candidate for bioelectronic interfacing with biological systems. However, despite recent advances, development both excellent properties in physiological environments remains lingering challenge. Here, we report bi-continuous hydrogel (BC-CPH) that simultaneously achieves high (over 11 S cm -1 ), stretchability 400%) fracture...

Blending conjugated polymers with insulating matrices is often utilized for engineering extrinsic properties in organic electronics. Semiconductor/insulator blends are typically processed to form a uniformly distributed network of conductive domains within the matrix, marrying electronic and physical from individual components. Understanding polymer-polymer interactions such systems thus crucial property co-optimization. One commonly overlooked parameters structural configuration insulator...
Using isoindigo-based polymers, this study investigates mixed ionic–electronic conduction in highly ordered conjugated polymers by systematically incorporating polar side chains, which promote ion insertion while preserving interchain stacking.
ABSTRACT Chronic wounds with impaired healing capability such as diabetic foot ulcers (DFU) are devastating complications in patients, inflicting rapidly growing clinical and economic burdens aging societies. Despite recent advances therapeutic approaches, limited benefits of the existing solutions highlight critical need for novel wound healing.
