net cord sensor
HOW DOES THIS TECHNOLOGY WORK?
Net cord sensor a sensor that turns vibrations into electrical energy, called a piezoelectrical device, similar to that used in a hi-fi speaker or microphone. It's attached to the top of the net and detects when it vibrates, to see whether a serve should be called a let or not.
WHERE WAS THIS TECHNOLOGY DISCOVERED/INVENTED?
The first ever version - introduced in 1974 - was simply the pick-up from an electric guitar.
DOES THIS TECHNOLOGY IMPROVE THE SPORT?
Net cord sensors help the umpire to know whether the ball, during a serve has touched the net.
HAS THIS TECHNOLOGY SPREAD TO OTHER PARTS OF THE WORLD?
The net cord sensor is a technology that is used throughout the world due to how very simple it is. It is used because it is a device that alters vibrations into a sound, meaning that it is simple and cheap to install into tennis nets. This makes a net cord sensor cheap and affordable throughout the world.
WHEN IS THIS TECHNOLOGY USED?
Net cord sensors are mainly used in training but can also be used in matches. This is because when a player practices they are not as piped up as they would be while playing a proper game; this is why they are used in game as well as in and actual tennis match.
