Based on electronics engineering design, the Biomedical Electronic Device Laboratory (BEDL) constructs tactile perception systems for both humans and robots, through which we conduct research on haptic feedback implementation and robotic tactile intelligence.

​

As part of our human-centered research, we utilize various tactile sensors to acquire and analyze tactile signals. By analyzing and quantifying fine signals collected from real objects, we generate Realistic Virtual Tactile Signals for virtual environments. We then study systems that deliver realistic kinesthetic and tactile feedback to the user through various actuation methods, such as vibration, electricity, and electro-osmosis.

​

This tactile perception expertise extends to the enhancement of robotic intelligence and hardware integration. We study vision-based and semiconductor-based tactile sensors, along with robotic skin sensor interfaces, to provide a foundation for robots to perceive their physical environment with precision. By physically integrating these tactile technologies into our custom-built robotic hand systems, we implement robotic tactile intelligence. Furthermore, we construct high-level robotic tactile perception systems through VLT (Vision-Language-Tactile) AI models that integrate multimodal data including vision, language, and touch to enhance object manipulation and safe human-robot interaction.
