Welcome to the Optofluidic and Energy Systems Laboratory at NUS !!!

Our research group investigates fundamentals of small-scale fluidic and interfacial phenomena such as electrowetting, water contact based electrification, and light-interacted microfluidic manipulation. With fundamental understanding in these areas, we further develop novel materials and optofluidic devices for the following applications:

1. Optics applications:

  • High-degree beam steering via liquid prisms
  • An optofluidic tunable Fresnel lens enabling 3D focal control

2. Energy (solar/water/material) applications:

  • Optofluidic sunlight manipulation technologies (solar energy collection, solar indoor lighting, solar spectrum splitting) for sustainable buildings
  • Water contact based energy harvesting (e.g. raindrop, waterfall, ocean wave, etc.) on a single-sided low-friction surface
  • High-capacitance dielectric and hydrophobic materials for low-voltage electrowetting applications

3. Water and bio applications:

  • Smartphone integrated optoelectrowetting (SiOEW) device as a low-cost portable tool for on-site and real-time water/air quality monitoring
  • Optical manipulation of small-scale objects: optical tweezers (OT), optoelectronic tweezers (OET), optoelectrowetting (OEW)
  • Pulse laser-driven high-speed biological sample generation and single-cell encapsulation
