And finally in 2010, a ball "CTRUS" was presented. It is transparent electronic ball, that does not need to be inflated. Moreover, its physical characteristics are comparable to conventional football ball. Inside this ball there is the construction of complex shape. As for the outside, "CTRUS" is covered with a shell of reinforced elastomer, making it more flexible than the previously used balls. It is also meant that CTRUS will convert kinetic energy into electrical so it will be lighted with different colors depending on the situation on the field.
That’s not the first such device that has been developed.
A ball with a small chip inside of it was presented on the exhibition CeBIT in 2003. Even then, this chip could cause the camera to track the flight of the ball automatically, or resolve disputed issues for goals, off-sides. The problem of developers was only in mounting the chip inside beefiest air ball.
In 2005 the company Adidas and Cairos Technologies together carried out and successfully tests their own version of the electronic ball that could determine its position on the field and transmit the coordinates of the judges with high accuracy. At the same time such chips were created for the football players.
In 2007 the electronic ball called Teamgei2t was introduced at the International Stadium in Yokohama. The ball has one unique feature, it signaled crossing the goal line with 100 % accuracy. The encrypted signal was transmitted on the clock of the official judges of the match. This version of the ball was tested at the World Cup - FIFA Club World Cup in Japan 2007. Despite considerable pressure during the game, chips built-in the balls did not receive any injuries. Externally the ball did not differ from normal balls.
