Australian opener David Warner has been training and playing games at this World Cup by using a sensor device on his bat that stores important data like back lift angle and maximum bat speed.

The International Cricket Council (ICC) had approved the usage of bat sensor back in 2017. But this is one of the first instances of a batsman employing the idea for the betterment of his game.

Based in Bangalore, a company named "Smart Cricket" has introduced its version of sensor chip device "Bat Sense" that Warner has been using to try and counter the threat of bowlers such as Jasprit Bumrah.

This chip is placed on the top of the bat handle, and the data generated on the chip gets stored in a mobile app through "cloud storage" till the batsman is hitting the ball.

It is learnt that Warner's bat sensor has made some interesting revelations about the work he put in to play Bumrah for Australia versus India during the World Cup clash on Sunday (June 9) at The Oval.

The angle of a backlift for Bumrah's slinger is expected to be around 120-125 degrees with the bat coming down from the first slip. However, for Bhuvneshwar Kumar the backlift needs to be in line with the keeper, and with spinners, that backlift angle changes to 160 degrees minimum and can go up to 175 degrees.

"Earlier, the coaches would depend on their natural instinct about angle of backlift or bat speed or the distance between the bat and body," former India keeper Deep Dasgupta, who is associated with the project, told PTI.

"I believe if accurate data can help coaches in guiding their players, then why not."

At the moment, the bat sensor technology is still in early stages where collecting data is of main priority.

"The data that will be available is of primary nature. Once a large chunk of data is collected across a cross section of players, it can be suitably processed by the coaches. Then players can accordingly change their game as per the available data," Deep concluded.
