Get Started

The development of the market for fitness trackers and activity monitors is driven by a desire to track, analyze and share data related to personal health and fitness. They provide feedback on exercise and health habits and must satisfy both fitness amateurs as well as professional athletes.

The main design challenges of a fitness tracker involve delivering low-power and high accuracy in a cost effective manner to allow tracking of general activity, specific exercises, heart rate and calories burned.

ST's best-in-class motion and environmental sensors, ultra-low-power, high performance microcontrollers, and state-of-the-art power management are the best choice in order to design the next generation of these personal wearable devices.
