Health Monitoring and Fitness Tracking – IR Product – BioMon Sensor SFH 7050

Compact OSRAM sensor improves fitness monitoring

First integrated optical sensor introduced by OSRAM Opto Semiconductors

fitness tracking 2OSRAM Opto Semiconductors has developed a new optical sensor for automatic fitness tracking. The SFH 7050 is OSRAM’s first integrated optical sensor. It is designed for use in mobile devices, such as smart watches and fitness armbands, and it simplifies personal heart rate or pulse rate measurements during jogging, for example. The sensor contains three light emitting diodes with different wavelengths, based on highly efficient chip technology. This helps save power and also offers high signal quality for particularly reliable measurements. A built-in photodetector receives the reflected optical signals and is separated from the emitters by an opaque barrier.


The three emitters built into the sensor have wavelengths of 530 nm (green), 660 nm (red) and 940 nm (infrared). These enable precise measurements of pulse at the wrist or fingertip and the oxygen content of the blood at the fingertip. The emitters can be controlled individually, which allows the sensor to be used for different applications. Green light has been established as the best option for measuring the pulse at the wrist. Red or infrared emitters are generally used for measuring the pulse at the finger and they can also measure the oxygen content of the blood (pulse oximetry).
