WBA Wireless Bioamplifier System

WBA Wireless Bioamplifier System

Wireless Full Bandwidth EMG Sensors and Desktop Receiver

<< New way to measure sEMG, EEG and ECG
<< This wireless EMG system offers complete measurement functionality setups with flexible setup

Three sensor configurations:

  • Fixed dry electrodes
  • Snap connectors
  • Pinch connectors
<< 4, 8 or 16 channels
<< Charging dock

The WBA system is ideal for measuring physiological signals in a motion analysis lab, sports training centre, hospital lab or occupational location. It is supplied either as a complete integrated system, or as the data acquisition component of an existing system.

Connections to External Systems

The WBA system is equipped with analog output for connection to data recording and analysis equipment.

Connections to motion analysis systems such as Vicon, MAC,Qualisys, Simi, CodaMotion, NDI, etc, can be easily made.

Use for MANY applications


One System, Many Applications

This full-featured, research-grade system is ideal for many different applications. Small and lightweight biosignal sensors are easy to place. Your patient or test subject can move about freely and easily. Measurement preparations are fast.

The batteries in all sensors are charged together in the supplied fast-charge recharger dock.

By turning on the sensors while still in the recharger dock, the sensor timing of all channels is synchronized.

  • Monitoring rehabilitation procedures
  • Neurophysiological monitoring
  • Biomechanics research
  • Motion analysis
  • Gait and posture analysis
  • Work and ergonomics analysis
  • Sports research

COMPLETE Tools for Signal Viewing and Analyzing

The system can be delivered with a computer interface and MegaWin PC-software so viewing and analyzing of data is available with one software tool.

Easy to use!

FULLY compatible with MegaWin Software                           

MegaWin software offers a versatile, easy-to-use data acquisition and analysis software platform with a full range of monitoring and analyzing features:

  • Personal data management and data base
  • Graphical intuitive configuration system using drag and drop, for defining different signal types
  • Protocol wizard for multiple applications
  • Data processing and analysis tool
  • Multiple on-line/real-time features for raw, averaged, biofeedback, sounds, FFT-spectrum fatigue analysis
  • Complete body 3D muscle/nerve maps (option)
  • Reporting

MegaWin includes management tools for system settings and easy-to-use protocols based measurement control. Protocols can be created easily and quickly with a step-by-step progressing wizard. Software includes anatomic muscle maps with electrode placement examples from each specific muscle.

MegaWin data files can be exported as a binary file, ASCII file and in Matlab-format for further analysis. C3D-format allows Matlab-format inputting MegaWin data into well equipped motion analysis systems. MegaWin also allows EDF (external data format) for export.
