• Mouthguard and Soft contact-lens biosensor

  Keyword： biosensor, MEMS
  Summary： Based on advanced polymer microelectromechanical systems (MEMS) techniques, a soft contact-lens biosensor have been developed . The biosensor provides novel biomonitoring such as glucose monitoring in tear fluids.
  

• Imaging system for analysis of human volatiles

  Keyword： biosensor, imaging device
  Summary： A imaging system for spatial distribution of volatile chemicals have been developed. The visualization system is expected to be used in future medical screening or dental health.
  

• The human volatilome sensors and monitoring system

  Keyword： biosniffer, biosensor
  Summary： High selective gas-sensors Bio-sniffer have been constructed with molecular recognition of enzyme in human liver. Potential applications of the bio-sniffer and nose includes halitosis analysis, breath alcohol and aldehyde measurement, environmental VOC monitoring, etc.
  

• Organic engine based on chemo-mechanical energy conversion

  Keyword： energy conversion
  Summary： A novel chemo-mechanical energy conversion system (organic engine) that utilizes enzyme reactions and active transport of chemicals have been constructed. Biomedical applications (chemical pumps, drug release systems, etc.) are also investigated.
