D-printed hydrogel is soft, and sometimes it can be tough. However, could it be hard? Here, researchers from Zhejiang University report a 3D photo-printable hard/soft switchable hydrogel composite, ...

Lee Group projects include applying biomimetic structural designs to create tough hydrogels that can potentially function as tissue adhesives or extracellular matrices for tissue repair and ...

They are usually soft and weak, but can be made hard and tough. Hydrogels are gels that have water as their main constituent. Lactic acid (LA), likely abundant on early Earth, can polymerize into ...

His research interest includes synthesis and characterization of tough polymeric hydrogels, wearable electronics/sensors, flexible batteries and soft actuators. He worked in a very interdisciplinary ...
