NeXus-32

Overview

The NeXus-32 is our top of the line and powerul QEEG system for biofeedback, neurofeedback, and physiological research.

Multimodal qEEG system

The NeXus-32 offers up to 24 channel qEEG functionality, 4 channels of electrophysiology for EEG, sEMG, ECG, and EOG, 3 channels of peripheral parameters like GSR, BVP, temperature, and respiration. The NeXus-32 is equipped with an oximetry input that also allows for trigger interfacing. To learn more about the trigger interfacing functionality, please take a look at our NeXus Trigger Interface.

Use the NeXus-32 in powerful multimodal research settings, but also as a versatile portable monitoring device. It is powered by batteries or through an AC power supply plug. It can communicate in real time with your computer wirelessly by using bluetooth technology, and it can also be connected to your computer using a fiber wire cable. You can also store your data on an SD flash card for more than 8 hours of physiological ambulant data. In spite of its many capabilities, the NeXus-32 can easily be worn on a belt.

Versatile and powerful solution

The NeXus-32 comes with the easy to use and highly customizable BioTrace+ software, with free lifetime updates. BioTrace+ is a complete software package for  a wide range of biofeedback and neurofeedback applications and physiological monitoring. Create reports with statistics or just export the data and use it for further analysis. The NeXus-32 set also includes power supply, 6 batteries, Bluetooth dongle, USB extender cable, Leather product case, fiber wire cable, Fiber optic to USB interface (FUSBI), and a protective carrying case.

Take a look at our physiological sensors and accessories to explore the full possibilities of the NeXus-32.

High quality and reliable signal recording

With the high medical grade connectors that lock-in, there is neither noise nor artifact when touching or pulling them. Artifacts through movement of cables or other external sources of noise are reduced to a minimum, because of cutting edge active noise cancellation technology and carbon coated cables. Prevention is better than cure; the goal is to prevent artifacts, not to delete them afterwards and thereby deleting valuable data as well. NeXus systems are built with high quality electronics. It is easy to get good and very reliable signals with less preparation time. No cables going to your computer, providing a high freedom of movement.
