If you have recently attended a music concert of a famous artist anywhere in the world, or have watched a video of that performance, you might have also noticed colourful wristbands that sync with the music and might be wondering how 1000s of these wristbands perfectly sync, adding another dimension to the party.
These are smart wristbands, which can be controlled remotely, and they only receive input from a specific source, which means, only the organisers of a concert will have control over it. They are now being used to ensure every individual attending these parties feels they are a part of the performance.
Depending on the brand, these smart wristbands will include multiple LEDs that can light up or breathe, a basic motherboard, a signal receiver, and a battery/cell to power the entire thing. Multiple brands offer these smart wristbands such as Pixmob, and these are commonly referred to as LED wristbands.
Depending on the concert and its theme, these LED wristbands will come in different sizes and shapes, and in most concerts, these are issued on a returnable basis, where the audience has to hand them over as soon as the show is over.
These are programmed and controlled wirelessly using radio signals, where a signal is sent to all the nearby LED wristbands to enable or disable the LED lights. Sometimes, the wristbands located in a certain section of the auditorium can be programmed to function differently than the rest, enabling a different effect, which is achieved using an infrared signal, the same signal that helps us control televisions and air conditioners using a remote.
According to Pixmob, a leading smart LED wristband company, it has wristbands that can display up to 16 million colours and can cover the full RGB spectrum.
In most concerts, these wristbands are included as a part of the experience. However, in some cases, especially in South Korea, where these types of wristbands have been common for the last few days, fans can buy them separately, and they are even paired to a specific seating location to ensure they perfectly sync with the theme.
Most of these LED wristbands are reusable, which also makes them eco-friendly and are also made using recycled plastic. They also include an easy-to-swap battery, and they remain in circulation, until and unless they are physically damaged.
However, without a proper transmitter, these LED wristbands are of no use, as these cannot be controlled manually. The next time you attend a concert that issues an LED wristband, you finally know what makes it work.
