Designed into Fujitsu’s Raku Raku Smartphone F-01L, the MAX30101 enables users to measure stress levels and arterial aging

SAN JOSE, Calif. and TOKYO—Maxim Integrated Products, Inc. recently reported 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.

“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 Limited, in a press release. “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.”

The MAX30101 is reported to enable accurate measurements of vital signs using sophisticated algorithms produced by Fujitsu Connected Technologies. The algorithms integrated into the F-01L enable heart-rate monitoring only; pulse oximetry is not enabled.

The heart-rate sensor is part of Maxim’s family of biosensor products for health-related use cases. By integrating various functions, the module is said to provide “a complete system solution” that eases the design-in process for mobile and wearable devices.

The MAX30101 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 always, Maxim said.

Communication is through a standard I2C-compatible interface, and it operates over the -40-degree Celsius to +85-degree Celsius temperature range.

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