Research Overview
Our laboratory focuses on fiber-optic sensing technologies,
including hetero-core fiber sensors, SPR/LSPR-based chemical and biosensors,
and optical sensing applications for healthcare and environmental monitoring.
We conduct research in the following four areas:
1. Hetero-core Fiber-Optic Sensors
Hetero-core structures enable highly sensitive detection of minute bending,
pressure, and displacement changes.
Applications
- Bending sensors (robotics, pressure monitoring)
- Acceleration sensors
- Biomedical monitoring (pulse, respiration)
- Swallowing function assessment
Keywords
Hetero-core fiber, bending/strain sensing, biomedical monitoring
2. SPR / LSPR Chemical & Biosensors
Surface plasmon resonance and localized SPR are used
for detecting gases, biomolecules, and chemical reactions.
Target analytes
- Gas sensors (H₂, NH₃, VOCs)
- Biosensing (Glucose, IgG, antigen-antibody reactions)
- Functional films (Pd, TiO₂, WO₃, Au nanoparticles)
Technologies
- Transfer Matrix Method (TMM)
- Thin-film multilayer design
3. Healthcare & Well-being Sensing
We develop low-burden, non-invasive sensing methods for
healthcare and well-being applications.
Examples
- Swallowing function assessment
- Respiratory and pulse monitoring
- Home healthcare applications
4. Photonic Device Design & Numerical Simulation
Optical behavior in fiber structures and multilayers
is analyzed through simulations and applied to device development.
