Elements of the football that today are tested are the deformation of the football when it is kicked or when the ball hits a surface. Two styles of footballs have been tested by the Sports Technology Research Group of Wolfson School of Mechanical and Manufacturing Engineering in Loughborough University; these two models are called the Basic FE model and the Developed FE model of the football. The basic model considered the ball as being a spherical shell with isotropic material properties. The developed model also utilised isotropic material properties but included an additional stiffer stitching seam region.
The game of soccer has evolved greatly over the years and the ball has evolved with it.  In days past, defenses played with as many as six men back.  Then things changed around the 1950s to allow when many teams played four forwards at one time!  Now, we are in a period where we see (sometimes) one natural forward in a team.  The changes that have happened in the game have oftentimes been a result of the changes to the soccer ball itself.  Through its many changes, it has allowed teams to change strategies.
Some additional information worth noting with this Adidas smart soccer ball is that you cannot use the sensor features for kicks once the ball is in motion. Users report you cannot use it for tracking stats associated with, for example, a drop kick. The ball must be sitting still on the ground before being kicked if you wish to track the statistics.
Though, a ball designed to be played virtually anywhere will have to sacrifice something to achieve that versatility. For the Brasilia, that sacrifice comes in the form of responsiveness. While the glossy finish may offer some protection, it also reduces your touch with the ball. A bladder made out of synthetic rubber-not to mention that TPU is only okay when it comes to touch in the first place, further compounds this effect.
The fact that this ball was not only tested but used in 2016 Euro qualification matches makes it a trusted choice. Its graphics are minimal with the majority of the surface being white in color. A hint of red and silver streaks breaks the monotony of the white yet maintains a simplistic appeal which appeals to the simplistic users. The graphic designs go against the panels which gives it a unique appeal. Its casing uses 100% PU leather and the panels are thermal-bonded which makes the surface smooth. Its bladder uses butyl material which improves air retention. The surface of the ball provides lower water absorption which contributes to its durability and gives it a better feel.
Well, panels are not any different component. Panels are the segments or octagon quilt that are seen outside the balls. Of course, nowadays you will find some other shapes besides octagon. FIFA official balls usually contain 32 panels. But nowadays you will also find 26, 18, 14, 8 or even 6 panels with different shapes and designs from those of conventional balls.

Adidas says its design was motivated by Russia's urban landscapes. It uses textured graphics and a metallic sheen to bring a modern look to the classic design. The ball is made of six panels of thermally bonded TPU and about 15% silicone. The materials allow for better trajectory, accuracy, responsiveness, and low water absorption. It also feels well-padded and slightly lighter than previous match balls.
