What it does
A non-invasive device for ENS that restores airflow perception via four passive structures—modulating resistance, rhythm, structural stability, and cold-sensory feedback.
Your inspiration
ENS patients often suffer not from low oxygen intake, but from the inability to feel air moving through their nose. I studied hundreds of patient self-reports and coping methods, revealing a shared goal: restoring friction, rhythm, or cold sensation to regain the feeling of breathing. This led to a systemic exploration of nasal structure, airflow mechanics, and sensory disruption—and ultimately, to a design that rebuilds perception from within.
How it works
The device consists of four passive modules: a flexible one-way micro-valve to introduce exhalation resistance; a tapered flow path to reshape rhythm and slow airflow; a magnetic traction system to expand the nasal valve angle; and a TRPM8-triggered cold-sensing layer for neural feedback. These components work in synergy—stabilizing structure, slowing flow, and activating sensation—without electronics, ensuring comfort and long-term usability.
Design process
Rather than following a linear idea, this design emerged through iterative elimination and reconstruction. From early experiments with menthol and vibration, I shifted toward structural airflow control inspired by EPAP devices, then added spiral ducts and tapered chambers to guide flow perception. Later, I integrated a soft magnetic expander to stabilize the nasal valve, and finally layered in cold-triggered microcapsules to rebuild the brain's sense of “air presence.” Each prototype tested one mechanism; the final form blends them all.
How it is different
Unlike nasal dilators or sleep plugs, this design addresses not just airflow volume but perceptual collapse in ENS. It recreates the sensation of breathing by combining friction, rhythm, structural expansion, and cold-stimulus pathways. Its flexible magnetic system avoids rigid nasal clips, while its cold-sensing layer provides sustained TRPM8 activation—without sprays or fatigue. It is fully passive, modular, wearable, and designed for chronic daily use.
Future plans
Next steps include modularizing each component for adjustable fit, refining materials for long-term biocompatibility, and establishing clinical collaboration with ENT and sleep medicine departments. The goal is to build a standardized system that adapts to different nasal anatomies and symptom severities. In the future, this device may evolve into a certified assistive tool for ENS, post-surgical sensory rehab, and rhythm-based breathing disorders—bridging design, perception, and medicine.
