Physiological data acquisition

Measure and analyze physiological signals from the human body and brain. Our wireless physiological data acquisition systems are integrated and easy to use. With NeXus and BioTrace+ Software we offer a powerful research tool to measure a wide range of physiological signals as a response to certain events, emotions and stimuli. Hundreds of universities, hospitals, and research centers are using our solutions for multimodal data acquisition.


Why NeXus by Mind Media?

  • Multimodal and integrated data acquisition from 4 to 32 channels
  • Sample rates up to 2.048 Hz in 24 bit resolution
  • Wireless Bluetooth for freedom in movement
  • USB for maximum sample rates and data quality
  • Active shielding for minimal noise and movement artifacts
  • Event trigger interface for synchronization
  • Card memory for ambulant recordings
  • Medical CE certified (IIa), FDA registered (II)
  • Export and import of several data formats like ASCII, EDF(+) or other formats
  • Flexible software for building own research designs or protocols

Interface for synchronization

In order to accurately synchronize events, triggers can be sent through the NeXus Trigger Interface (NTI). The NTI monitors stimuli/events and synchronizes these with the physiological signals. Different types of events can be monitored simultaneously. The NTI measures all of its inputs with 2048 samples/second. By use of RS232, the NeXus systems can also acquire events sent by E-prime and Presentation.

Event triggering

Developer Tools & SDK

Flexible software for building own research designs or protocols. BioTrace+ has highly configurable screens and a script editor. In the screen editor mode, screens can be customized or built from scratch.

Software Development Kit (SDK) for even more interfacing and editing options. The SDK provides you with tools for custom programming within BioTrace+ or for creating your own C++ program interfacing with the raw data of the NeXus.
