Universities Develop Full-Body Haptic Suit for Immersive VR/AR Experiences

A collaborative research team from Hanyang University, the University of Seoul, and Sungkyunkwan University has achieved a breakthrough in virtual and augmented reality interfaces by developing the world's first full-body, lightweight, electric haptic suit, named TESS (Tactile Electric Stimulation Suit).

This innovative suit delivers realistic tactile sensations across the entire body within VR and AR environments. It also holds potential for therapeutic applications through nerve stimulation. The development addresses the growing demand for immersive content, where touch is considered the next key interface beyond sight and sound. Existing haptic devices often suffer from bulkiness, rigidity, and poor wearability due to heavy motor structures and thick materials, limiting their ability to precisely mimic complex human movements.

This technology is a platform technology that fundamentally solves the limitations of weight, rigidity, and scalability of existing haptic systems.

The research team overcame these challenges by creating a highly stretchable electronic material platform. This platform combines conductive hydrogels with silver-based fiber interconnectors and polyurethane fibers, offering excellent resistance to dehydration. The result is a suit that provides the comfort of everyday clothing with high adhesion, ensuring stable electro-tactile signal transmission even during sweating and movement.

A significant advancement is the suit's adaptive haptic feedback system. It precisely reflects real-time changes in skin impedance across different body parts, individual body types, and movements. This allows for uniform and stable stimulation tailored to each user, delivering a personalized and immersive tactile experience. The TESS suit utilizes electro-tactile stimulation, applying minute electrical currents to the skin to simulate texture, pressure, and touch, potentially revolutionizing fields from physical AI and remote surgery to robotic training and digital therapeutics.
