Summary: The solution treatment of PEDOT:PSS-coated textiles with DMSO and methanol enhanced crystallization of PEDOT chains, improved contact with fibers, and effectively removed the insulating PSS part, resulting in highly conductive textiles with reduced sheet resistance. The conductive textiles achieved a maximum temperature of 133 degrees C within 20 seconds at a low applied voltage of 3 V, showing promise for multi-functional wearable heater applications.

Summary: Piezoresistive nanocomposite fibers have been widely studied for their high sensitivities at large deformations, but little attention has been paid to their behavior at low strains. In this study, wet-spun piezoresistive nanocomposite fibers were investigated for their electromechanical properties and resistance signal stability during cyclic loading. The results showed a linear relationship between resistance and strain, with the working factor increasing with filler loading. The gauge factors of the fibers varied inversely with the working factor. The endurance limit of the fibers in the elastic regime was also predicted using fatigue theory.

Summary: The demand for flexible electronic devices has increased due to the high interest in electronic textiles (e-textiles). This has led to a growing interest in flexible energy storage devices to power e-textiles. This study introduces the use of electrospray deposition (ESD) technique for depositing PEDOT:PSS on conductive carbon yarns, creating flexible electrodes with a high surface area. The optimized deposition conditions of PEDOT:PSS have been evaluated for its electrochemical performance in a 1D symmetric supercapacitor with a cellulose-based gel as an electrolyte and separator, showing high specific capacitance, excellent cyclability, and outstanding bending capability.

Summary: A convenient and green method for obtaining graphene/PDMS film pressure sensor was demonstrated through vacuum deaeration mixing and screen printing. Graphene was dispersed in PDMS without traditional mechanical stirring and the aid of organic solvents. By optimizing the ratio of graphene, PDMS, and curing agent, excellent sensing performances are achieved. Furthermore, 25 sensing units were integrated into intelligent insoles for wearable electronics, which showed higher recognition accuracy in various movements. With the efficient preparation process and remarkable sensing performance, graphene-based pressure sensor has promising applications in healthcare.

Summary: In this study, the J-V curves of PEDOT:PSS were examined, revealing nonlinear behavior and hysteresis loop-like patterns. The potential of PEDOT:PSS for resistive random access memory (ReRAM) was demonstrated. The resistive switching effect was explained using a Schottky barrier and space-charge-limited conduction model. Dielectric and electrical characteristics were also analyzed, and a modified Debye function and Jonscher's power law were used for data fitting.
