Bioprobe 1 Optical Heart Rate Module

Salutron-Tech-Logo_bioprobe1

The fastest way to ‘quick start’ optical heart rate.

This ‘system’ module integrates our unique optical architecture with a dedicated accelerometer and an arm mcu with a preloaded Bioprobe OP – delivering to wearable devices fully processed and validated heart rate information.

Bioprobe 1 contains Salutron’s unique optical architecture.  This proprietary design consists of four high resolution optical detectors surrounding the single probe beam, enabling high heart rate performance and low power.  This system maximizes both the amount of photons reaching the skin from the single probe beam and the quantity of reflected photons being detected.

In any optical heart rate monitoring system, not all the photons from the emitter(s) reach the skin, and of those that do, some are absorbed and the rest are reflected in all directions within the detector assembly.

Bioprobe 1’s optics maximize the amount of photons reaching the skin and the quantity of reflected photons detected, resulting in high resolution and signal to noise ratio of heart signals.
