BVP Sensor 

The BVP Sensor, also called Blood Volume Pulse Sensor, can be used to measure the relative change in blood flow resulting from the contraction of the heart. In other words vasoconstriction and vasodilatation. It uses light-based technology, also known as a PPG (photoplethysmography). Combine with respiration for Heart Rate Variability (HRV) training. BVP is a very efficient way of quickly measuring heart rate and relative blood flow. For a more precise measurement of heart rate, it is recommended to apply an ECG with the ExG Sensor.

The Pulse/HR Sensor for NeXus offers:

  • Easy finger clip-on mechanism
  • Durability

The magnitude of this systematic variability seems to reflect a healthy alternation between two autonomic influences of the heartbeat: sympathetic and parasympathetic. By calming one's emotional state and by making the breathing slower and more regular, the HRV can be increased, at least temporarily.

This sensor is usually placed on a finger of the non-dominant hand. Make sure not to move the sensor too much since this will influence your signal and create artefacts/noise.

Use the Respiration Sensor in combination with the BVP Sensor in order to monitor both breathing and heart rate for several biofeedback applications.

Although the BVP sensor is a very efficient way of quickly measuring heart rate, you can alternately do an ECG/EKG with our EXG Sensor. Because of carbon technology and active noise cancellation, this sensor is less susceptible to artefacts. The BVP sensor is often preferred though because of ease of use and efficiency.
