“…Flexible and transparent electrodes, characterized by their flexibility and transparency, are widely utilized in the domains of flexible electronics, optoelectronics, and energy. [125][126][127] These electrodes are designed to maintain consecutive conductivity even when subjected to deformation, such as bending or stretching. Furthermore, achieving high resolution in the assembled patterns is critical, which necessitates minimizing the width of wires to ensure the transparency of the electrodes.…”

The assembly of functional materials into microstructures, which extends unique features such as enlarged specific surface areas, effective conduction paths, higher material utilization ratios, and ordered alignment compared to continuous films, has gained prominence in various fields. Achieving high performance in electronics requires cooperation among building blocks, fabrication methods, and device design. However, the remaining challenge is obtaining highly regular and large‐scale patterns with controllable assembly methods while maximizing device performances. Manipulating functional materials with liquid assistance is a feasible approach to realizing controllable dewetting, regular molecule packing, and customized performances. This review focuses on the recent advances in preparing and applying liquid‐induced microstructures. The predominant preparation technologies are summarized, including flow‐enabled assembly, nanoimprint lithography, and capillary‐bridge‐mediated assembly. Furthermore, diverse applications of various microstructure‐based electronics, such as flexible and transparent electrodes, organic field‐effect transistors, gas sensors, photodetectors, and solar cells, are demonstrated.

With the swift advancement of wearable electronics and artificial intelligence, the integration of electronic devices with the human body has advanced significantly, leading to enhanced real-time health monitoring and remote disease diagnosis. Despite progress in developing stretchable materials with skin-like mechanical properties, there remains a need for materials that also exhibit high optical transparency. Supercapacitors, as promising energy storage devices, offer advantages such as portability, long cycle life, and rapid charge/discharge rates, but achieving high capacity, stretchability, and transparency simultaneously remains challenging. This study combines the stretchable, transparent polymer PEDOT:PSS with MnO2 nanoparticles to develop high-performance, stretchable, and transparent supercapacitors. PEDOT:PSS films were deposited on a PDMS substrate using a spin-coating method, followed by electrochemical deposition of MnO2 nanoparticles. This method ensured that the nanosized MnO2 particles were uniformly distributed, maintaining the transparency and stretchability of PEDOT:PSS. The resulting PEDOT:PSS/MnO2 nanoparticle electrodes were gathered into a symmetric device using a LiCl/PVA gel electrolyte, achieving an areal capacitance of 1.14 mF cm−2 at 71.2% transparency and maintaining 89.92% capacitance after 5000 cycles of 20% strain. This work presents a scalable and economical technique to manufacturing supercapacitors that combine high capacity, transparency, and mechanical stretchability, suggesting potential applications in wearable electronics.

In the evolving landscape of portable electronics, there is a critical demand for components that meld stretchability with optical transparency, especially in supercapacitors. Traditional materials fall short in harmonizing conductivity, stretchability, transparency, and capacity. Although poly(3,4-ethylenedioxythiophene):poly(styrene sulfonate) (PEDOT:PSS) stands out as an exemplary candidate, further performance enhancements are necessary to meet the demands of practical applications. This study presents an innovative and effective method for enhancing electrochemical properties by homogeneously incorporating Ru(III) into PEDOT:PSS. These Ru(III) PEDOT:PSS complexes are readily synthesized by dipping PEDOT:PSS films in RuCl3 solution for no longer than one minute, leveraging the high specific capacitance of Ru(III) while minimizing interference with transmittance. The supercapacitor made with this Ru(III) PEDOT:PSS complex demonstrated an areal capacitance of 1.62 mF cm−2 at a transmittance of 73.5%, which was 155% higher than that of the supercapacitor made with PEDOT:PSS under comparable transparency. Notably, the supercapacitor retained 87.8% of its initial capacitance even under 20% tensile strain across 20,000 cycles. This work presents a blueprint for developing stretchable and transparent supercapacitors, marking a significant stride toward next-generation wearable electronics.
