Abstract Gelatin methacryloyl (GelMA) is a widely used hydrogel with skin‐derived gelatin acting as the main constituent. However, GelMA has not been in development of wearable biosensors, which are emerging devices that enable personalized healthcare monitoring. This work highlights potential for biosensing applications by demonstrating fully solution‐processable and transparent capacitive tactile sensor microstructured core dielectric layer. A robust chemical bonding reliable encapsulation...
Electrospinning, a process that converts solution or melt droplet into an ejected jet under high electric field, is well-established technique to produce one-dimensional (1D) fibers two-dimensional (2D) randomly arranged fibrous meshes. Nevertheless, the direct electrospinning of controllable three-dimensional (3D) architectures still nascent technology. Here, we apply near-field (NFES) directly write arbitrarily shaped 3D structures through consistent and spatially controlled fiber-by-fiber...
Flexible capacitive tactile sensors show great promise in personalized healthcare monitoring and human–machine interfaces, but their practical application is normally hindered because they rarely possess the required comprehensive performance, that is, high pressure sensitivity fast response within a broad range, structure robustness, performance consistency, etc. This paper aims to engineer flexible with highly ordered porous dielectric microstructures 3D-printing-based fully...
