Flexible Electronic Device Laboratory

We explore diverse inorganic semiconductor materials (Si, GaAs, GaN, 2D material) and develop diverse flexible electronic device, including transistors, diodes, LEDs, sensors and actuators. Our research targets flexible electronic platforms, such as flexible displays, wearable electronics, biomedical devices and VR haptic interfaces. 

1. Next generation flexible semiconductor devices, sensors and actuators

We develop various flexible electronic devices based on the following materials:

- Electronics: Si-based MOSFET, GaN-based HEMT, GaAs-based HBT and Schottky diode

- Optoelectronics: GaN-based micro-LED, Si photodiode

- Sensors and actuators: biosensors, actuators for VR haptics, composite devices

2. Bio-integrated wearable and implantable electronics

Our flexible electronics technology overcomes the mechanical mismatch between biological systems (soft and curvilinear) and traditional semiconductor devices (rigid and planar). We seek to implement our technology into wearable and implantable applications, ranging from skin-attachable haptics for virtual reality to neural implants for brain-computer interface.

3. Eco-friendly biodegradable electronics

Conventional electronics are typically made of non-renewable, non-biodegradable, and sometimes toxic materials. We are interested in creating high-performance flexible electronics based on inorganic semiconductors combined with biodegradable, ecofriendly substrate materials for potential replacement of traditional devices.
