About

Dr. Jingjing Qiu has pioneered the intersection of 3D printing and soft electronics, with a primary focus on developing advanced functional hydrogels for wearable technology. Her landmark 2019 study on "Ultrasensitive Wearable Strain Sensors of 3D Printing Tough and Conductive Hydrogels" (44 citations) represents a significant breakthrough in additive manufacturing of flexible electronics. In this work, Dr. Qiu ingeniously combined thermo-responsive agar with ionic-responsive alginate to create a dual-crosslinked hydrogel system that dramatically improved print shape fidelity. By enhancing ink viscosity through agar incorporation, she optimized rheological properties for precise 3D printing of conductive structures. This innovation enabled the fabrication of tough, stretchable sensors capable of detecting subtle human motions with exceptional sensitivity. Her approach addresses critical challenges in wearable device manufacturing—balancing mechanical robustness with electrical conductivity while maintaining printability. Dr. Qiu's contributions have opened new pathways for customizing soft sensors through additive manufacturing, with implications for healthcare monitoring, human-machine interfaces, and soft robotics. Her work continues to influence the development of next-generation wearable electronics that seamlessly integrate with the human body.
