Physiology Recording

BIOPAC MP160 wireless physiology system

Technical Specifications:

  • Provide simultaneous measurement of different physiological data
  • Subunits: EMG, SKT, RSPEC, PPGED, EEG, NICO
    • EMG amplifier: Electromyogram (EMG) measures electrical potential generated by muscle cells
    • SKT amplifier: measure skin surface temperature and monitor respiration
    • RSPEC amplifier: able to record both respiration and electrocardiogram
    • PPGED amplifier:  1. Photo Plethysmogram (PPG) measures heart rate, inter-beat interval and vasodilation/constriction data. 2. Electrodermal Activity (EDA) measures skin conductance activity/ response
    • EEG amplifier: Electroencephalogram (EEG) measures electrical potential generated by the brain
    • NICO amplifier: measure impedance magnitude; can be used to study beat-by-beat impedance, stroke volume and cardiac output measurements
