About

Junsang Lee is a rising leader in the development of bioinspired soft materials and wearable sensor technologies. His research centers on biodegradable shape-memory polymers, ultrasensitive strain sensors, and conductive hydrogels—materials designed to bridge the gap between mechanical performance and biomedical functionality. Lee’s most cited work, “Principles for Controlling the Shape Recovery and Degradation Behavior of Biodegradable Shape-Memory Polymers in Biomedical Applications” (2021, 36 citations), provides foundational design rules for polymers that can both change shape and safely degrade inside the body. He further advanced the field with “Ultrasensitive crack-based strain sensors” (2022, 29 citations), which elucidates the mechanism behind highly sensitive, skin-like sensors for health monitoring. In 2025, his spider silk-inspired conductive hydrogels (23 citations) demonstrated a breakthrough in combining toughness with environmental resilience through dense hierarchical structuring. Lee also introduced “Spongy Ag Foam for Soft and Stretchable Strain Gauges” (2024), addressing key challenges like hysteresis and response time in wearable electronics. His work is shaping next-generation materials for soft robotics, implantable devices, and real-time physiological sensing.
