The power of technology: MEMS sensors in wearable devices help athletes win gold and silver medals

The 2024 Paris Olympics has come to a successful conclusion, and the "technological style" shining inside and outside the stadium has become a highlight of this Olympics. The "digital" presentation inside and outside the stadium of this Olympics is not only a feast of sports competition, but also a grand event of technological innovation.

The integration of technology and innovation has not only improved the competitive level and viewing experience of the Olympics, but also promoted the continuous development of sports and provided solid support for mankind's pursuit of the goal of "higher, faster, stronger".

In today’s global focus on sports, technological innovations such as MEMS (micro-electromechanical systems) sensors are almost ubiquitous. MEMS sensors embedded in wearable devices such as smart watches and fitness trackers can effectively monitor and improve sports performance. From daily training to major sporting events, these small but powerful sensors can be used to monitor progress and receive real-time feedback.

Precision in athletics and cycling

In the world of competitive sports, every millisecond and every centimeter counts. Imagine a high jumper preparing for an international competition, constantly looking for ways to improve his jumping technique. MEMS sensors embedded in his sportswear can accurately capture the height and distance data of each jump and provide real-time feedback, helping him make immediate adjustments to optimize his posture and technique.

Cyclists rely on maintaining an optimal cadence and power output to ensure peak performance. With MEMS sensors, they can optimize pedaling efficiency and power distribution. The data collected by the sensors helps to make real-time adjustments that not only improve overall performance but also provide a competitive advantage.

How MEMS Sensor Technology Works

STMicroelectronics is a leader in MEMS sensor technology, integrating micro-electromechanical systems with electronic circuits to measure a variety of physical parameters such as acceleration, angular velocity, direction and pressure. For example, accelerometers can calculate speed, measure the rate of change of an object's speed, detect specific postures and track body movements, providing athletes with accurate and reliable data.

Optimize training for swimming and racket sports

In competitive swimming, an efficient turn can be the difference between a race and a loss. Accurate depth measurement is essential for underwater challenges, and MEMS sensors play an important role in this area. For example, STMicroelectronics waterproof pressure sensors can provide real-time data on turns and depth, helping athletes optimize their performance and efficiency in the water. By embedding MEMS sensors in sportswear or goggles, swimmers can monitor their performance during training.

In addition, coaches can use this data to adjust training programs to help athletes improve performance and competitive advantage in the pool or open water.

In racket sports such as tennis, table tennis and baseball, speed and accuracy of the ball are key. MEMS sensors embedded in the racket or bat can provide detailed data about posture and impact force, helping athletes to quickly adjust and improve their hitting techniques.

Real-time feedback in football and adaptive training

In contact sports such as football, impact force monitoring is critical to player safety and performance, as is tracking the ball's air speed and spin rate. High-G accelerometer MEMS sensors embedded in helmets are able to capture detailed impact data, while sophisticated smart ball tracking capabilities enhance the spectator viewing experience.

In addition, they can provide important information about the force and direction of the collision, helping coaches and medical staff monitor the safety of players. This data is also an important reference for developing training and game strategies. For example, if a player is hit hard, the data can prompt immediate medical treatment to ensure the player's health.

MEMS sensors are used in a wide range of sports. Whether a cyclist is adjusting their stride cadence, a swimmer is optimizing their underwater turn, or a tennis player is perfecting their swing, MEMS sensors, including inertial measurement units (IMUs), provide the real-time data needed to make immediate improvements and achieve improved performance and competitive advantage over time.

It is undeniable that MEMS sensors embedded in wearable technology are changing the landscape of competitive sports. They can provide precise performance monitoring and optimize training plans through real-time feedback. As technology continues to advance, the role of MEMS sensors in improving sports performance will become increasingly significant, paving the way for future athletes.
