Abstract Myocardial infarction (MI) causes cell death, disrupts electrical activity, triggers arrhythmia, and results in heart failure, whereby 50–60% of MI‐associated deaths manifest as sudden cardiac (SCD). The most effective therapy for SCD prevention is implantable cardioverter defibrillators (ICDs). However, ICDs contribute to adverse remodeling disease progression do not prevent arrhythmia. This work develops an injectable collagen‐PEDOT:PSS (poly(3,4‐ethylenedioxythiophene) polystyrene sulfonate) hydrogel that protects infarcted hearts against ventricular tachycardia (VT) can be combined with human induced pluripotent stem (hiPSC)‐cardiomyocytes promote partial remuscularization. PEDOT:PSS improves collagen gel formation, micromorphology, conductivity. hiPSC‐cardiomyocytes hydrogels exhibit near‐adult sarcomeric length, improved contractility, enhanced calcium handling, conduction velocity. RNA‐sequencing data indicate maturation cell‐matrix interactions. Injecting mouse decreases VT the levels healthy hearts. Collectively, offer a versatile platform treating injuries.

Supercapacitors offer notable properties as energy storage devices, providing high power density and fast charging discharging while maintaining a long cycling lifetime. Although poly(3,4-ethylenedioxythiophene) doped with poly(4-styrenesulfonate) (PEDOT/PSS) has become gold standard among organic electronics materials, researchers are still investigating ways to further improve its capacitive characteristics. In this work, we introduced Nafion an alternative polymeric counterion PSS form highly PEDOT/Nafion; advantageous supercapacitive were improved by treatment either dimethyl sulfoxide or ethylene glycol. Accordingly, electrochemical characterization of PEDOT/Nafion films revealed their areal capacitance (22 mF cm–2 at 10 mV/s) low charge transfer resistance (∼380 Ω), together excellent volumetric (74 F cm–3), Coulombic efficiency (99%), 23.1 ± 1.5 mWh cm–3 0.5 W cm–3, resulting from more effective ion diffusion inside the conductive film, confirmed results spectroscopic studies. A proof-of-concept symmetric supercapacitor based on was characterized specific approximately 15.7 g–1 impressive long-term stability (Coulombic ∼99% ∼98.7% after 1000 charging/discharging cycles), overperforming device PEDOT/PSS.

Hydrogels with a combination of mechanical flexibility and good electrical conductivity hold significant potential for various applications. Nonetheless, it is inevitable that water-based conductive hydrogels lose their elasticity at extremely low temperatures, severely limiting utilization in ultralow temperature environments, such as those Arctic/Antarctic exploration. In this study, we developed hydrogel based on double network cross-linking strategy incorporated silk fibroin (SF) poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT:PSS) within lithium bromide (LiBr) solution, which shows exceptional antifreezing (-108 °C freezing point) excellent (16.33 S m-1). The obtained SF/PEDOT:PSS/LiBr (SPL) stable reliable response to wide range deformations (compression: 0.5-60%; tensile: 1.0-100%), short response/recovery time approximately 70 ms. More importantly, the displays well-maintained conductivity, robust properties, dependable sensing capabilities, even under temperatures -80 °C. For proof concept, demonstrated applications SPL detecting body movements, monitoring climate conditions, ensuring information security environments. results indicate promising candidate fabricating flexible sensors, particularly well-suited use challenging scenarios.
