About

Xiaojiang Liu is an innovative materials scientist and engineer whose research sits at the dynamic intersection of advanced manufacturing, smart materials, and functional electronics. His work spans three interconnected domains: 3D and 4D printing of functional materials, stimuli-responsive hydrogels, and flexible/wearable electronics systems. Liu's most influential contributions include a highly cited review on 3D-printed anisotropic polymer materials (269 citations), which illuminated their transformative potential in aerospace, soft robotics, and sensing applications, and a landmark survey on stimuli-responsive shape-morphing hydrogels (209 citations) that mapped the rapidly evolving landscape of 4D-printed smart structures inspired by biological systems. His work on piezoelectric-driven self-powered electrochromic supercapacitors (107 citations) demonstrated elegant integration of energy harvesting with wearable technology. More recently, Liu has pushed the boundaries of micro-scale fabrication, developing conductive photoresists for two-photon polymerization 3D printing and pioneering capillarity-assisted liquid metal patterning for sophisticated flexible electronics. His investigations into high-resolution 4D printing further underscore his commitment to overcoming fundamental manufacturing constraints. With over 640 cumulative citations, Liu's research is shaping next-generation adaptive materials and intelligent devices across robotics, bioelectronics, and human-machine interfaces.
