About

Longtao Ji is a leading researcher in the emerging field of 4D printing and smart metamaterials, with a focus on shape memory polymers (SMPs). His work bridges advanced manufacturing and programmable material behavior, enabling structures that change shape or function over time in response to external stimuli. Ji’s most influential contribution is his pioneering study on 4D printed origami metamaterials with tunable compression-twist behavior and customizable stress-strain curves, which has garnered 216 citations and stands as a landmark in the field. This work demonstrates how geometric design and material intelligence can be combined to create adaptive mechanical responses. In a related study, Ji investigated the compression behavior of 4D printed reentrant honeycomb structures using both experimental and finite element analysis, further advancing the understanding of auxetic metamaterials fabricated via SMP-based 4D printing. His research has significant implications for deployable aerospace structures, soft robotics, and biomedical devices. With a growing citation impact, Longtao Ji is recognized as a key innovator in smart materials and additive manufacturing.
