I design tactile sensor structures and electronics to help robots perceive contact. I estimate force and contact position from capacitance signals and evaluate performance against reference sensors.
I have extended the three-axis sensing principle of a compact fingertip sensor to a gripper contact surface and am also simulating palm electrode structures. In wearable robotics research, I developed tension/grasp-force measurement devices and actuator control.
