Technology

PulseOn technology is based on optical measurement of blood flow under the skin. Our patented optical sensor includes green and infra-red LEDs which illuminate the skin and the small capillary vessels close to it, and an electro-optical cell (photodetector) which detects the light which is back-scattered from the skin and tissue. When the heart pumps, the blood flow varies according to the heart’s pumping frequency. PulseOn’s sensor detects this variation from the optical signal and translates the data into an accurate heart rate reading with its sophisticated algorithms.

We use the most advanced sensor hardware available to optimize the signal-to-noise ratio and ambient light cancellation for the best accurate low power heart rate monitoring – up to beat-to-beat accuracy with 6 ms resolution.

Multi-wavelength technology.  PulseOn uses different wavelengths of light to illuminate your skin in different depths. With intelligent algorithms this allows us to adapt to changing conditions, including physiological, anatomical and other dynamic variations; making PulseOn less sensitive to variations in e.g. skin color. This also allows us to optimize power consumption and minimize user disturbance e.g. during night.

Technology

Mechanic design. Firm contact of the sensor to the skin is essential in ensuring the accuracy in optical heart rate monitoring – any movement of the sensor against the skin tissue affect the acquired heart rate signal, causing increased movement artefacts and ambient light disturbance. PulseOn’s mechanical design guide and several years and products of expertise in designing an optimal sensor layout will ensure the best performance in different conditions and use cases. Combined with the intelligent algorithms, all disturbances to heart rate accuracy and reliability can be minimized.
