EEG technology is expanding rapidly into wearable, consumer, and long-term monitoring applications, yet the electrode systems powering it have not kept pace. Wet electrodes require messy gels and labor-intensive setup. Semi-dry alternatives leak and degrade quickly. Dry electrodes suffer from high impedance and discomfort. The result is inconsistent signal quality, patient discomfort, and systemic bias across demographics, particularly for users with diverse hair types.
This dry electrode technology combines the signal fidelity of traditional wet electrodes with the simplicity of a gel-free, saline-free design. Its multilayer architecture, built around a conductive silicone surface and an elastic polymer core with a branched internal wire geometry, delivers low impedance, strong signal-to-noise ratio, and reliable conformity to scalp contours. Unlike existing alternatives that degrade quickly or introduce friction in clinical workflows, this reusable, cost-effective platform is designed for extended wear across diverse users, making it a practical foundation for both clinical diagnostics and next-generation wearable neurotechnology.
The NeuTrode is an innovative and customizable 'dry' electrode that increases the signal-to-noise ratio, providing higher quality biosignals across multiple applications.
