The 2024 European Championship in Germany is in full swing, and with the development of technology, the application of advanced technologies in football matches is becoming increasingly widespread, such as Video Assistant Referee (VAR), Hawkeye technique, etc.

This year's European Championship is also full of black technology, with the biggest highlight being the built-in sensing chip used in official matches. UEFA stated that this new technology will help capture every element of football and play a role in video referee decision-making.

It is reported that the chip (sensor) is located in the central position inside the football and connected to the shell through wires. Due to the weight of the built-in chip being only 14 grams, there is almost no weight difference compared to traditional football, and it will not affect the movement speed and game of the football.

The above device is responsible for recording the position and movement of the ball, and can monitor the contact between the outside world and the ball at a frequency of 500 times per second, which is 10 times faster than the cameras used in sports stadiums. It can promptly determine whether a player has committed a handball foul. On the field of play, when VAR reminds of a foul, looking back at the video can clearly display the signal fluctuations captured by the built-in chip when the player handballs.

At the same time, the above technologies can also quickly upload player position information, combined with AI artificial intelligence technology, further supporting semi-automatic offside recognition technology (SAOT).

The technology of built-in chips in football has been applied in the last Qatar World Cup and has shown impressive performance. At that time, the famous Portuguese football star Cristiano Ronaldo was suspected of scoring a header during the game, but chip monitoring showed that the ball did not touch the star's head, so the goal was awarded to Ronaldo's teammates.

At this year's European Championship, football's built-in chips also played an important role. During the group stage, Belgium suffered a 0-1 defeat to Slovakia. The Belgian player scored two goals, but the first VAR ruled that the player was offside. The second time, the football's built-in chip recognized the player's handball, so both goals were invalid.

Based on factors such as promoting fair competition and improving the athletic level of athletes, the relationship between sports events and the chip industry is becoming increasingly close. At the European Championship, football's built-in chips mainly assist referee work through data collection and analysis. In addition, the chip can also provide scientific basis for athlete training, such as smart sports shoes, smart wristbands, smart glasses, VR/AR equipment, which can provide comprehensive and accurate sports monitoring and auxiliary functions for athletes, creating an immersive training and competition experience.
