Overview

The NeXus-4 is a small and high-end biofeedback and neurofeedback system which is totally suitable for professional grade physiological monitoring, and clinical applications.

Starter system for biofeedback and neurofeedback

Our most affordable 4 channel system can be used for all kinds of biofeedback and neurofeedback applications by measuring a wide variety of signals such as brainwaves (EEG), muscle tension, heart rate, relative blood flow, skin conductance, respiration, temperature, and many more. The NeXus-4 is so small it fits in your pocket and it communicates wirelessly with your computer using bluetooth technology. Thanks to its portability the NeXus-4 provides the user with a great deal of freedom in movement during a session. Its built-in flash memory of 64 MB can store more than 8 hours of physiological ambulant data.

Versatile and flexible solution

The NeXus-4 comes with the easy to use and highy customizable BioTrace+ software, with free lifetime updates. BioTrace+ is a complete software package for physiological monitoring and a wide range of biofeedback and neurofeedback applications. Create reports with statistics or just export the data and use it for further analysis. The NeXus-4 also includes 4 batteries, Bluetooth dongle, leather system case, manuals, and a protective carrying case.

Take a look at our solutions and our physiological sensors to explore the full possibilities of the NeXus-4.

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.
