The WHOOP 4.0 uses Nordic’s nRF52840 SoC to supervise sensors and relay data to smartphone app

U.S.-based human performance company, WHOOP, has launched a health monitoring wearable that can perform continuous physiological data monitoring for up to five days without requiring recharge. The ‘WHOOP 4.0’ monitors the wearer’s heart rate, heart rate variability, blood oxygen saturation, sleep data, strain, and skin temperature, and can be worn on the wrist, bicep, or discreetly enclosed within specially designed ‘WHOOP Body’ technical garments, that include fitness and lifestyle options.

Powerful health insights

Powered by Nordic’s nRF52840 Bluetooth® LE SoC, the 64 MHz, 32-bit Arm® Cortex® M4 processor with floating point unit (FPU) provides ample computational resource to power WHOOP proprietary algorithms and supervise the on-board sensors. The data is relayed to a smartphone using Bluetooth LE wireless connectivity and accessible via the ‘WHOOP’ app where members can get health insights, see improvements and irregularities, as well as download health records.
