The Invisible Connection

Engineering Capacitive Non-Contact Neural Sensing Systems

Capture the brain’s whispers without ever touching the skin.

Strategic Objectives

• Master the physics of high-impedance capacitive coupling.

• Design advanced low-noise amplifiers for ultra-weak signal detection.

• Implement robust electromagnetic shielding against ambient interference.

• Develop wearable neural interfaces that work through hair and clothing.

The Core Challenge

Traditional neural interfaces require conductive gels and direct skin contact, limiting long-term monitoring and user comfort in real-world environments.
