Tiny motion-sensing and data-processing chips from STMicroelectronics have enabled the ultimate activity tracker designed for swimmers by swimmers with positioning accuracy and real-time audio feedback from XMetrics, an innovative wearable-tech maker.
 
The ergonomic and lightweight device, which shares the company’s name, clips onto the goggles’ band at the back of the swimmer’s head. ST’s 9-axis MEMS inertial module senses the body movements and provides precise data analyzed by the XMetrics algorithm, executed inside an STM32F4 32-bit microcontroller, to detect the swimming style and determine the number of laps and strokes, stroke frequency and quality, flip-turn efficacy, speed, and elapsed time.
 
Swimmers get instant information on their performance through waterproof earphones so they know exactly how they are doing at any turn or stop during the swimming session.
 
XMetrics software and apps enable swimmers to program their training schedule and customize the audio feedback. Synchronization via tablet or smartphone is automatic. Out of the water, users can analyze every aspect of their swim using advanced graphical tools and share results with their coach and friends.
 
“ST’s leading-edge Internet-of-Things (IoT) technologies helped us realize our dream of developing an easy-to-use, powerful Smart-Things trainer that delivers personal-coach attention to every swimmer,” said Andrea Rinaldo, XMetrics CEO, a swim coach and former professional swimmer.
