Visitors to the NASA Space Center. Kennedy will soon see an “intelligent” pavement consisting of a piezoelectric tile that accumulates its own energy and can glow at night. Today in the stone jungles of megacities, sidewalks take up a lot of space, so scientists decided to give them modern technology.
In the beginning, special coatings appeared, absorbing solar energy, turning it into a beautiful backlight. Pedestrian paths were created that generated electricity from the impact of passers-by and even emitted Wi-Fi signals. Specialists of the NASA Space Center, creating their “smart pavement” decided to combine all the best that was invented earlier.
The $ 2 million pavement consists of 1,000 tiles located on an area of 3,700 square meters. They form the mosaic images of the Earth, Mars, the Moon and the ISS. Each tile contains electronic boards, six small solar panels, a battery, LEDs, Bluetooth, a Wi-Fi transmitter, microcontrollers and a piezoelectric element. All this is placed in the cavity in a special concrete and covered with a solid glass tile. Piezoelectric elements generate energy from the mechanical action of the steps.
Along with multi-colored lighting, tiles also pass on to mobile phones of passers-by information about the latest achievements in the field of space technology. The system is completely autonomous, thanks to piezoelectric elements, solar panels and lithium batteries, where all the stored energy is stored.
The main goal of the project is to introduce the technologies of “smart” cities of the future. Installations like this can be used to illuminate places where visitors can receive interesting information in real time.
