MAX30101 enables users to measure stress levels and arterial aging


San Jose, Calif. and Tokyo, Japan — Maxim Integrated Products, Inc. announced that its MAX30101 heart-rate sensor is integrated into the new Raku Raku Smartphone F-01L from Fujitsu Connected Technologies Limited. The smartphone, which measures heart rate and sleep patterns, can be used for applications such as pedometers. With the MAX30101, the smartphone can also measure stress levels and arterial aging (the aging of blood vessels). A popular series for seniors, the Raku Raku Smartphone F-01L has been designed so that even those who are using a smartphone for the first time can use it comfortably.

The MAX30101 enables accurate measurements of vital signs using sophisticated algorithms* produced by Fujitsu Connected Technologies. It is part of Maxim’s family of biosensor products for health-related use cases. By integrating various functions, the module provides a complete system solution to ease the design-in process for mobile and wearable devices. In addition, it operates on a single 1.8V power supply and a separate 5.0V power supply for the internal LEDs. The module can be shut down through software with near-zero standby current, allowing the power rails to remain powered at all times. Communication is through a standard I2C-compatible interface, and it operates over the -40°C to +85°C temperature range.

*Algorithms integrated into F-01L enables heart-rate monitoring only; pulse oximetry is not enabled

MAX30101 Key Advantages

  • Small Size: Available in a tiny (5.6mm × 3.3mm × 1.55mm) 14-pin optical module
  • Low Power: Programmable sample rate and LED current provide ultra-low-power operation for mobile devices (< 1mW) and ultra-low shutdown current (0.7μA, typical)
  • Ease of Design: Easy implementation due to the integration of internal LEDs, photodetectors, optical elements and low-noise electronics with ambient light rejection

Availability and Pricing

  • The MAX30101 is available at Maxim’s website for $4.08 (1000-up, FOB USA); also available from authorized distributors
