Pulse oximeter and heart rate sensor module provides ultra-low power solution for wearables

System designers can speed time to market for wearable and healthcare products with the MAX30102 pulse oximeter and heart rate integrated sensor module from Maxim Integrated Products, Inc.

The integrated pulse oximetry and heart rate monitor module is the lowest power solution on the market today. It provides a complete system solution to save space and ease the design-in process for mobile and wearable devices.

Wearable equipment for vital-sign monitoring is rapidly evolving. With system-on-chip (SoC) and integrated module solutions rapidly replacing discrete, multicomponent designs, analog integration is at the heart of these changes. The MAX30102 integrates red and IR LEDs to modulate LED pulses for oxygen saturation (SpO2) and heart rate measurements.

Key Advantages

  • Ultra-low power: The lowest power solution on the market; Operates on a single 1.8V power supply and a separate 5V power supply for the internal LEDs
  • Space savings: Maintains a very small solution size without sacrificing optical or electrical performance; Integrates internal LEDs, photodetectors, optical elements, and low-noise electronics with ambient light rejection
  • Ease of design: Evaluation platform with the integrated module and an accelerometer provides a solution for customers to quickly evaluate the module

“Maxim is committed to providing innovative wearable solutions for customers,” said Andrew Baker, executive director for Industrial and Healthcare Products at Maxim Integrated. “Our IP and knowledge for these applications allows us to integrate multiple technologies in a tiny, low power package.”

“Healthcare and wearable technology is a rapidly growing market,” said Susie Inouye, research director at Databeans. “Maxim’s analog and microcontroller technology is well-positioned to be a key player in this market.”

Availability and pricing

  • Available in a tiny 14-pin optical module (5.6mm x 3.3mm x 1.55mm).
  • Specified over the -40-degree Celsius to +85-degree Celsius temperature range.
  • Pricing starts at $4.13 (1000-up, FOB USA).
  • An evaluation board is available.

A demo of the MAX30102 will be available at the Wearable EXPO 2016 (January 13-15, 2016) in Tokyo Big Sight, Japan. Maxim will be located at booth E-23-4 within the Marubun (distributor) booth.
