Summary: This study proposes a simple and rapid method for preparing patterned liquid-metal-enabled universal soft electronics (PLUS-E). The PLUS-E exhibits rapid fabrication, excellent stretchability, and high forming accuracy. The stability of PLUS-E on 3D surfaces is improved by using low-fluidity liquid metal composites. The finite element simulation accurately forecasts the deformation and resistance changes of the PLUS-E and provides guidance for device design. Various sensors developed using this method have demonstrated stable and reliable signal measurements in real-world applications.

Summary: Ionogels are promising materials for flexible electronics due to their continuous conductive phase, high thermal and chemical stability. However, a large amount of ionic liquid is required to get high conductivity, resulting in a sharp decline in the mechanical properties. Therefore, it is a great challenge to prepare ionogels with both high conductivity and mechanical properties, which is important for their practical applications.

Summary: This study proposes a new manufacturing method using high-precision direct printing technology to print circuits on hard, arbitrarily curved surfaces. The method involves using 3D projection technology to map a 2D planar functional circuit onto a 3D digital curved surface and then directly printing the integrated circuit on the complex surface. Optimal printing parameters are determined by exploring the main factors affecting molding quality and electrical conductivity of curved surface circuits. The feasibility and potential of the proposed technology are demonstrated through simple examples.
