GENERAL DESCRIPTION
Heartbeats are triggered by bioelectrical
signals of very low amplitude generated by
a special set of cells in the heart (the SA
node). Electrocardiography (ECG) enables
the translation of these electrical signals into
numerical values, enabling them to be used
in a wide array of applications. Our sensor
allow data acquisition not only at the chest
(“on-the-person”), but also at the hand
palms (“off-the-person”), and works both
with pre-gelled and most types of dry
electrodes. The bipolar configuration is ideal
for low noise. Here are a few examples:
