# 7. Device Description

The Neuroelectrics device, Enobio Wireless EEG, performs electroencephalographic measurements with non-invasive technology.

Enobio is a wireless, battery-operated and portable electrophysiology sensor system for the recording of the electroencephalogram (EEG). It has been designed for use in a clinical environment or hospital.. Enobio use must be controlled by specialized medical personnel able to guarantee the correct recording.

ENOBIO WIRELESS EEG, consists of three models designated as the 8, 20 and 32 channels. ENOBIO WIRELESS EEG has a sampling rate of 500 SPS, it works in a bandwidth from 0 to 125Hz (DC coupled) and it provides a resolution of 24 bits - 0.05μV. Enobio is capable of acquiring a variety of electrophysiological signals. These signals include EEG, EOG, ECG and EMG.

The Enobio system is primarily made up of the following three items:

{5}------------------------------------------------

- Necbox (amplifier, transmitter and control box),
- the neoprene cap with the electrodes and
- the NIC software.

The Necbox, which has a data amplifier, connects directly via Wi-Fi to the Neuroelectrics Instrument Controller (NIC) software running on a computer. The EEG data is streamed through the standard Wi-Fi band, and the standard Wi-Fi operating distance range is 10 meters. In all situations the amplifiers store a copy of the data locally to allow for data back-up. This amplifier provides storage and subsequent transmission of data that is not transferred live when the amplifier is in out of range situations.

# 8. Substantial Equivalence Discussion

The following table compares the ENOBIO WIRELESS EEG to the predicate device with respect to indications for use, principles of operation, technological characteristics, materials, and performance testing. The comparison of the devices provides more detailed information regarding the basis for the determination of substantial equivalence. The subject device does not raise any new issues of safety or effectiveness based on the similarities to the predicate device.
