Intended use

Philips health band measures, tracks, and analyzes
movement and physiological parameters. These
metrics are intended as input for behavioral
change programs for managing lifestyle of
individuals with risk of or affected by weight and
activity related chronic disease.
Investigation of these parameters is used in the
assessment of the physiological state of a person
and their daily physical activity level. For people at
risk of these lifestyle related chronic diseases or
patients with a pre-existing condition, the
continuous monitoring of these parameters can
give insight in changes of heart rate and daily
physical activity.
The non-medical purpose is measurement of:
steps, resting respiration rate and sleep patterns,
and providing: automatic activity recognition
(cycling, running, walking), a heart rate zone
indication and sedentary behavior alerting, for
wellness purposes.
The device is intended for 24/7 use in daily life,
both indoor and outdoor, by adults of 18 years and
older.
The Philips health band is intended to be used by
one adult consumer only.
Operating principle
The Philips health band is a wrist-worn activity
(accelerometer) and heart rate measurement
device that uses the Opticardiogram technology.
The general operating principle of this
Opticardiogram technology is based on LEDs
emitting light through the surface of the skin. Part
of that light is reflected and collected by the photo
sensor.
The blood flow in the arteries is driven by the heart
beating and pumping blood. The blood flow
changes over time. Therefore, the amount of light
reflected varies over time. The sensor in the health
band collects this change in reflection of light.
