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, ...

They are usually soft and weak, but can be made hard and tough. Hydrogels are gels that have water as their main constituent. Inspired by the entangled structure of double-network hydrogels ...

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 ...

Post-traumatic osteoarthritis (PTOA) is a condition that affects joints after an injury. Current treatments focus on relieving symptoms, but do not prevent or stop the progression of the condition.

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 ...
