STMicroelectronics reports that its ultra-low-power STM32L MCU and 3-axis accelerometer are enabling the Nike+ FuelBand health and fitness monitoring wristband that can track a user's activity, including running, walking, dancing, and dozens of everyday actions.

The device can differentiate between simple gestures and active motions, a function that requires complex signal-processing capabilities. Also, the FuelBand is always on since wearers might jump into action at any time. The device features 120 LEDs comprising the display and a "Fuel" indicator that racks up points as the wearer exercises.

At the heart of the FuelBand is ST's ultra-low power STM32L MCU which provides 32bit performance and processing capacity required for advanced signal processing. The MCU is said to deliver real-time responsiveness, power efficiency, and highly integrated peripherals and memory required for the most demanding embedded applications.

The Nike+ FuelBand weighs less than one ounce (28.35g), including the batteries, in a sleek black shell. Relying on ST's super-efficient low-power technology, the wristband is capable of operating for up to four fully active days without recharging.
