HOW SCOSCHE® RHYTHM WORKS
Blood is constantly moving through the human body and consequently the amount of blood under the
skin at any given point is constantly changing. The main forces of blood movement are the heart pumping
and physical body movements. ScoSche® RHYTHM armband detects blood movement by shining light
onto the skin and measuring the amount of light that is absorbed by the skin.

WIRELESS PULSE MONITOR
For iPhone, iPad, iPod touch and Android
In addition RHYTHM uses an accelerometer similar to what is used in popular gaming controllers to detect
body movement and then subtracts the movement from the light measurement. All of the data collected from
this process is sent to the user’s iPhone or iPod touch for further filtering and signal processing. The final
output is displayed on the iPhone or iPod touch as the user's pulse.
