GENERAL DESCRIPTION
Our Blood Volume Pulse (BVP) sensor is an
optical, non-invasive sensor that measures
cardiovascular dynamics by detecting
changes in the arterial translucency. When
the heart pumps blood the arteries become
more opaque, allow less light to pass from
the emitter on the sensor through to the
receiver. The BVP sensor has a plastic clip-
on housing for placement on the finger, which
houses the light emitter and detector, and
also minimizes interferences from external
light sources. Together with the Heart Rate
Variability (HRV) plugin on our OpenSignals
software, one can easily record and extract
meaningful information from the collected
data. Examples:
