A pulse oximeter and heart rate integrated sensor module speeding time to market for wearable and healthcare products has been unveiled by Maxim Integrated. The ultra-low power solution also saves space and eases the design-in process for these devices.
This is in view of the fact that system-on-chip (SoC) and integrated module solutions are rapidly replacing discrete, multicomponent designs for the development of compact wearable equipment for vital-sign monitoring.
The module has red and IR LEDs to modulate LED pulses for oxygen saturation (SpO2) and heart rate measurements. One of the major benefits of the module is its extended battery life. The module operates on a single 1.8V power supply and a separate 5V power supply needed for the internal LEDs.
Integrating internal LEDs, photodetectors, optical elements, and low-noise electronics with ambient light rejection, the module achieves space savings and maintains a very small solution size without sacrificing optical or electrical performance.
Further, to ease design process, an evaluation platform with the integrated module and an accelerometer is provided. Specified over the -40-degree Celsius to +85-degree Celsius temperature range, the module is available in a tiny 14-pin package (5.6mm x 3.3mm x 1.55mm).
A demo of the MAX30102 will be available at the Wearable EXPO 2016 (January 13-15, 2016) in Tokyo Big Sight, Japan.
