Maxim’s heart-rate sensor features in Fujitsu’s Raku Raku Smartphone F-01L
The smartphone, which measures heart rate and sleep patterns, can also measure stress levels and arterial aging. A popular series for seniors, the Raku Raku Smartphone F-01L has been designed to be easy to operate.
The MAX30101 provides a system solution to ease the design-in process for mobile and wearable devices. It operates on a single 1.8V power supply and requires 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-degree Celsius to +85-degree Celsius temperature range.
