Simplify EEG. Amplify Insights.

The Patch EEG is a wireless, wearable system that collects EEG data from seated, supine, or moving subjects in natural environments and situations. The system is optimized to provide high-quality EEG with minimal forehead preparation. This is achieved through utilizing specialized HydroFlex™ electrodes and advanced amplification techniques that reject ambient electrical noise.

The Patch EEG records data to a Micro SD card and can also stream the signal real-time into the CGX Flowpoint desktop software using the Patch EEG Plug-In.


Highly specialized snap mechanisms and a disposable semi-solid gel electrode align to various head shapes and sizes. The Patch EEG produces raw EEG data at 500Hz with 24-bit fidelity which can be visualized and recorded in Flowpoint. Flowpoint also allows you to further process your raw data using an ever-growing selection of validated processing and feature-extraction Plug-Ins.

Intended Use: For Research Purposes Only

Wireless Amplifier:

• 2 EEG Acquisition Channels: Captures essential brain activity data with a focus on simplicity and effectiveness.
• 24-bit A/D Resolution: Provides high-precision, simultaneous sampling for accurate data interpretation.
