BioMon Sensor Enables The Development of Health and Fitness Tracking Devices
For developers looking to develop wearable devices that can monitor and record heart rate and blood oxygen levels. Measuring only 4.7 x 2.5 x 0.9 mm, the tiny BioMon optoelectronic sensor from OSRAM Opto Semiconductors, has been developed for integration into wearable devices such as fitness trackers and watches. Furthermore, the BioMon sensor is currently available from ILS in three variants, each of which is available mounted on a reference design board that will enable early stage development and prototyping.
The heart rate and oxygen level monitoring is achieved through the transmission and detection of green and red light. Green light transmitters are used for pulse rate measurement at the wrist, whereas red or infrared emitters are used for pulse rate measurement on the finger, as they can also measure the oxygen content of the blood (pulse oximetry). In combination with a photodiode, the infrared LED can also be used as a proximity sensor.
The BioMon features a light barrier to block any internal optical crosstalk, therefore improving the signal-to-noise ratio, and measurements begin automatically when the sensor comes into contact with the skin and stop automatically once the sensor is removed from the skin.
Each BioMon variant has a different set of characteristics, so that the sensor can be used for a wide variety of applications. In addition to this, ILS engineers are available to offer technical support and provide assistance with both product design and prototyping.
ILS is a division of Intelligent Group Solutions Ltd (IGS) a well-established and respected industry leading display and opto-electronics solutions provider. Much of IGS’ business comes from providing semi-custom or custom products both in component and sub-assembly form. ILS/IGS is a privately owned company and the owners are fully involved in the running of the business. All the senior staff have been involved with the opto-electronics industry for at least 15 years and are dedicated to ensuring that ILS is an innovative and highly successful operation.
