Pulse watch technology
Pulse rate monitors
S-Pulse™ is Salutron's patented heart
rate sensing technology designed to measure the electrical signals
on your skin in the same manner that an EKG or electrocardiogram does.
While the Smarthealth™ Pulse rate watch
attaches to your wrist like any other watch, it does not measure or
sense your pulse at your wrist. It instead uses S-PulseTM patented
technology to sense your heart rate - pulse rate by measuring your EKG signal.

The S-Pulse technology measures the electronic signals passing through your body that result from the beating of your heart. You may
be familiar with the EKG waveform from either personal experience while at the hospital, or from watching popular television medical shows. It is this very same signal
that S-PulseTM sensing technology measures.
S-Pulse monitor will perform differently on people of various ages, skin types, body types, EKG or electro-cardiogram signal strengths
and so on.
In the Smarthealth pulse monitor watch, this measurement is obtained by the Pulse rate watch’s three metal sensors. The back metal plate of the Pulse Watch is
actually a primary sensor that can measure these electronic signals off your wrist. The EKG monitoring is done when you place your fingers from one hand onto the two
top sensors of the Pulse monitor Watch attached to your opposite wrist. This creates an electrical loop across your body that the Pulse Watch can now read
In Salutron's OEM circuit
board applications, S-PulseTM technology is installed
by leading brand name manufacturers in their health & fitness
equipment - such as treadmills, stationary bikes, and elliptical
exercise machines. In these applications you simply touch
a metal sensor with each hand to obtain your heart
rate on the machine display.
