Welcome to Functional Soft Materials Laboratory!
Our main interest lies in creating new functionalities in soft materials, thereby finding useful applications, such as soft electronic/energy devices, actuators, microfluidics, sensors, etc.

Soft materials studied in our lab include, but not limited to, hydrogels, polymers, liquid metals and elastomers.

The on-going projects are listed below;
- Flexible wire/fiber chemical sensor
- Microfluidic hydrogel platform for water purification and 
- 3D-conducting hydrogels for electrode application in 
  electrochemical systems
- Liquid metal-based electronic/energy devices

If you are interested in our research or collaboration opportunity, please contact us via the email address below.
