Research Topic
- Brain Implant
Our lab specializes in cutting-edge brain engineering research, focusing on the development of the Stealthy Neural Recorder and the Multi-Deformable Dopamine Sensor. The Stealthy Neural Recorder is designed to precisely capture and analyze neural activity with high resolution, offering valuable insights into brain function and potential treatments for neurological disorders. Additionally, the Multi-Deformable Dopamine Sensor enables real-time monitoring of dopamine levels, even under varying physical conditions, which is crucial for research and treatment of dopamine-related diseases such as Parkinson's. Through these innovations, our lab aims to advance the understanding and management of complex brain disorders.

- Digital Health Care
Our lab focuses on extending the lifespan of continuous glucose monitoring (CGM) devices. We work on optimizing enzyme immobilization and bioresorbable polymer coatings to improve sensor stability and accuracy. We also develop wireless transmission and packaging methods for reliable long-term glucose monitoring. To ensure practicality, we conduct experiments on large mammals and research ways to enhance clinical application.

- Semiconductor
Our lab conducts research on semiconductors, focusing on the fabrication of Light Emitting Devices (LEDs). We work on creating micro-LED arrays using GaAs (Red) and GaN (Blue) epitaxial wafers. To achieve this, we employ a range of advanced equipment, including ICP-RIE, sputter systems, photolithography tools, and PECVD. The fabricated micro-LEDs are mainly utilized in bio-applications. For instance, Blue micro-LEDs are used in implantable neural probes for optogenetics, while Red micro-LEDs are employed in PPG and SpO2 measurements.

- Wearable Robot
Our lab is researching robotics and artificial legs, developing technology that creates more natural and active movement by seamlessly connecting humans and robots. Traditional wearable robots have been limited in how freely they can move based on the user’s intentions, so we are combining the central nervous system, wearable robots, and artificial prostheses into one integrated system that naturally operates according to the user's intent and provides immediate feedback. Our ultimate goal is to use our research in lower limb movement control to help amputees lead more active and independent lives, ultimately enhancing individual independence and quality of life and contributing to a society where everyone has the right to pursue happiness.
