Reserach overview
Pioneering Transient Iontronics for Sustainable Electronics
Our research establishes bioderived ionic liquids as a core platform for “Transient Iontronics”—a new class of electronic and ionic systems that operate with high functionality and disappear harmlessly in water or the environment.
By integrating biomass-derived ionic materials with soft matter, two-dimensional materials, and transient device architectures, we bridge fundamental materials chemistry with sensing, energy storage, and soft robotic applications.
BIODERIVED IONIC LIQUIDS (FOUNDATION)
We pioneered bioderived ionic liquids that enable transient ionics, introducing the first biomass-based ionic liquids incorporating alkali metal ions. These materials are fully dissolvable in water while maintaining high ionic conductivity, forming the foundation of all subsequent transient sensing and energy storage devices.

TRANSIENT FLEXIBLE IONIC DEVICES (Sensing)
Based on bioderived ionic liquids, we develop biodegradable temperature and ionic sensors with dramatically enhanced sensitivity. By molecular and ionic design, our sensors achieve up to an order-of-magnitude sensitivity improvement over conventional ionic sensing systems.

TRANSIENT ENERGY STORAGE (Energy)
We extend transient ionics to energy storage by developing fully biodegradable Mg-based air batteries. These devices demonstrate capacities while completely degrading after operation, highlighting the versatility of bioderived ionic materials beyond sensing applications.
