DSI-24 EEG

Weareable DSI-24 system is an EEG system designed for use scientific and engineering research enviroment. The core technology of the sistem consist of ultra-high impedance dry sensor interface (DSI) that work through normale hair and require no prior skin preparation, nor the use of conductive gel to facilitate elettrical contact with the scalp.

DSI-24 is designed for easy and confortable measurament of high fidelity EEG signals in laboratory enviroment, and relaying the eeg data to an external pc (Trasmitted either via blue tooth or wired micro-usb cable to a pc. Some DSI system included internal memory (up to 60 hours continuos recording).
