Users enabled to measure stress levels and arterial ageing

It has been announced by Maxim Integrated Products that its MAX30101 heart-rate sensor is integrated into the new Raku Raku Smartphone F-01L from Fujitsu Connected Technologies. 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 ageing (the ageing 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. 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 five volt 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.

Key features:

  • Small size: Available in a tiny (5.6x3.3x1.55mm) 14-pin optical module.
  • Low power: Programmable sample rate and LED current provide ultra-low-power operation for mobile devices (less than 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.

“It is our great pleasure to have our Raku Raku Smartphone F-01L equipped with the MAX30101,” said Naohide Kushige, Deputy Head of Business Unit and General Manager of Product Division at Fujitsu Connected Technologies. “This adoption has enabled the acquisition of new vital-sign data, leading to further improvement of applications in the Raku Raku Smartphone F-01L to support users’ health. We expect it to make people more conscious about health and help them lead a healthier life.”

Andrew Baker, Managing Director, Industrial and Healthcare Business Unit at Maxim Integrated, added: “The adoption of the MAX30101 into this popular smartphone is a significant step toward extending important vital-sign measurement functions to a wider population. By empowering smartphone users with mobile access to healthcare data, our technology is enabling a healthier world.”

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