Polymeric nanocomposite-based microstructures are valuable in soft electronics, robotics, and bioelectronics due to their superior performance and form factor. Traditional methods like photolithography and 3D printing are slow and costly. We propose a one-step direct printing technique to create microdome morphologies influenced by the Marangoni effect and nanoparticle interactions. By controlling ink viscosity, conductivity, and substrate temperature, we fabricate 64-pixel microdome array pressure sensors on flexible substrates. Applied to a robot's finger, these sensors enable precise liquid control and stable grasping. We also develop a stretchable pressure sensor array, showing potential as artificial skin. This method reduces time and cost, offering a scalable way to produce advanced microstructures and marking a pivotal advancement for soft technologies.
