Summary: This study introduces a convenient method for transferring perovskite patterns to different surfaces using a removable polymer, enabling integration of perovskite devices. The transfer method allows fabrication of a perovskite image sensor array on soft contact lenses and heterogeneous integration of a perovskite photodetector array with pressure-sensitive silicon transistors, creating a multiplexed sensing platform.

Summary: We present a high-throughput method for identifying and characterizing individual nanowires, and for designing electrode patterns with high alignment accuracy. Our method utilizes an optimized marker system called LithoTag, which allows for nanometer-scale position determination of nanostructures. By incorporating computer vision algorithms, we can obtain location and property data for individual nanowires. Experimental results demonstrate the effectiveness of this method in automating nanodevice processing and improving fabrication efficiency.

Summary: In this study, an innovative design of a new array microdroplet parallel-generation device based on fluid inertial force using a capillary glass needle is proposed. The device, using an electromagnetic actuator as the power source, consists of a 9-channel parallel array of glass needles that independently feed different solutions to avoid cross-contamination. The study investigates the homogeneity of droplet arrays, stability of the device, and the factors influencing microdroplet size, and develops a prediction model for droplet size, demonstrating the potential of the device for high precision and low-volume microdroplet-array generation.

Summary: This study proposes an assembly strategy for stretchable sensing devices, which involves compressed air-modulated alignment of silver nanowires (AgNWs) and printing transfer to a silicone elastomer. The assembly of AgNWs is achieved at the air-droplet interface through convective flow induced by compressed air, resulting in excellent alignment and packing. The oriented and densely packed AgNWs exhibit a lower and uniform electrical resistance compared to random AgNWs networks. The assembled AgNW networks are then transferred to the printed elastomer patterns using direct ink writing. Excellent electrical properties, wide electrical response range, high repeatability, and antibacterial property are demonstrated, highlighting the potential of wearable sensors.

Summary: Metasurfaces, a versatile platform for manipulating light waves using nanostructures, have the potential to greatly reduce the size of conventional optical elements. However, current metasurfaces are mainly demonstrated on bulky and thick substrates, which limits their application scenarios. A polymer-assisted transfer technique is developed to decouple the fabrication substrate from the target application, allowing the transfer of thin metasurfaces onto different substrates. This technique enables the thinnest dielectric metalens and opens up new opportunities for integrated multilayer metasurfaces and heterogeneous integration with nonconventional substrates and electronic/photonic devices.

Summary: Experimental study on the breakup of liquid bridges composed of aqueous Poly(acrylic acid) solutions reveals that for polymer concentrations exceeding a threshold, the contact line on the surface with the highest receding contact angle fully retracts before the liquid bridge capillary breakup occurs, causing the liquid to remain on the opposing surface. This behavior is attributed to the competition between thinning of the bridge neck and receding of the contact line on the surface with lower receding contact angle.

Summary: By coassembling W18O49 and V2O5 nanowires, a novel multicolor electrochromic device is demonstrated, which shows dynamic color change upon application of different electrochemical biases. The transparency and color of the device can be easily controlled by manipulating the layers and ratios of coassembled nanowires, allowing for the fabrication of different patterns with corresponding masks. This solid electrochromic device assembled from nanowires has significant potentials in smart windows and multicolor electrochromic displays.
