The Royal Academy of Engineering in the united kingdom has come up with a list of the seven engineering wonders of the 21st century.

The list was compiled with input from experts and a panel drawn from the academy’s programs for young engineers. The goal is to raise awareness of the wide range of positions in engineering, the Academy said.

Gore-Tex Fabric

Gore-Tex Fabric is waterproof and breathable allowing perspiration to pass through. Bound to clothing and footwear, it reduces the use of waterproofing sprays and waxes that were previously applied as they wear out.



Hawk-Eye is a computer system that “visually tracks the trajectory of a ball and gives a profile of the statistically most likely path of the movement”, as described by the Academy. It is most especially in sports such as tennis and football as a way to accurately referee tight calls.

Dolby Atmos

Atmos allows sound to move almost anywhere in a theater. Traditional stereo surround sound, such as that used for Star Wars in 1977, gives sound from only a few angles. Dolby Atmos allows artists to for the treatment of specific sounds as individual audio objects, which can be “precisely placed and be moved by the soundtrack maker everywhere in the cinema is three-dimensional space, which makes the cinematic experience much more immersive,” the Academy said.

Apple’s mobile phone “was launched, a mobile communications revolution in 2007,” says the Academy. The iPhone introduced the world of apps, and puts the internet in your pocket.

It is also “a revolution in the user interface” and the “simplicity brought a whole new audience on smart devices.”


YouTube has democratized video distribution, according to the Academy. The video-sharing service, has internet video “from a relatively small service to something used by all and paved the way… for services such as Netflix and Amazon Prime.”

3D printed bone implants

For bone implants, 3D printing is used for creating a “custom structures and jetties, made of ceramic, similar to natural bone.” And new bone can grow around and even the integration with the implant. These techniques are used in surgery to the jaw and face.

Clean water

“Diarrhea caused by dirty water and poor sanitation kills a child under the age of five every two minutes,” the Academy said, adding that globally one in six people still have no access to clean water. Technical innovation is of crucial importance in the water supply plumbing and distribution, and treatment.


New efforts include recycling, energy from the sludge of the treatment to the development of smart filters made of graphene, according to the Academy.
