Problem addressed

Underneath the ear skin there are rich vascular network and sensory nerve branches, hence the developed 3D auricular healthcare device has provided a electronic platform for collecting real-time multi-point auricular bio-signals as a new type of human health indicator by full-auricle bio-sensing and stimulation for the first time.

Innovation

An ultra-curved 3D ear-conformable human-machine interface was built by nano-material additive manufacturing for aull-auricle multi-channel bio-sensing and stimulating.
Algorithms for visualizing full-auricle spatiotemporal bio-signals by 3D contour map
Personalized design for users

Key impact

This technology enables high-density multi-point bio-sensing and stimulating across the entire ear auricles
A 3D ear-conformable human-machine interface is built to ensure high repeatability, stability and reliability during bio-signals acquisition
This multi-functional platform can simultaneously sense or stimulate multiple real-time physical signals (such as skin impedance, temperature, hydration, pressure, etc.) in auricular skin
Easy to wear, can be functionally integrated into headsets

Application

Monitor different human physiological changes during daily activities like exercising, sleeping or working
Diagnose patient’s health condition with different stages or track therapy effectiveness with Traditional Chinese Medicine
Perform mechanical/electrical auricular treatment
Monitor human emotional and mental changes
