About

Hojung Choi is a leading researcher in soft robotics and tactile sensing, with a focus on enabling dexterous robotic manipulation through advanced sensor and haptic technologies. Their work centers on developing novel capacitive sensors and haptic devices that can perceive and apply multiaxial forces—including normal and shear—critical for tasks requiring nuanced touch. Choi’s most-cited paper, "Additively manufactured micro-lattice dielectrics for multiaxial capacitive sensors" (2024, 44 citations), introduces a groundbreaking fabrication technique that overcomes planar design constraints, creating soft sensors capable of detecting complex forces for applications in robotic manipulation and human performance monitoring. Another key contribution, "Dynamically Reconfigurable Tactile Sensor for Robotic Manipulation" (2020, 40 citations), presents a tactile sensor with an array of "nibs" for reliable traction on wet or slippery objects, directly addressing real-world challenges in mobile robotics. Choi has also advanced haptic feedback with a 3-degree-of-freedom device for directional shear cues on the forearm, and pioneered force-informed action extraction for dexterous manipulation in "DexForce" (2025). Their work on tactile-informed action primitives mitigates jamming in dense clutter, showcasing a practical impact on robotic retrieval tasks. With a growing citation record and innovations spanning sensor design, deep learning for touch gesture classification, and haptic interfaces, Choi is shaping the future of tactile robotics.
