Remember that I recently published an entry talking about the Google science fair, where teenagers from all over the world are invited to present inventions of all kinds, in a competition where the best ideas are awarded with sums as juicy as $ 15,000. .
The shoe that generates energy when walking
Well, last month one of the young participants (and already among the finalists) of the Google science fair has become a media sensation thanks to the invention he has presented. Is about Angelo Casimiro, a 15-year-old boy from the Philippines who has shown the world his invention, which consists of insoles that can be placed on your shoes, and are capable of generating energy while you walk, enough to charge a cell phone or any another device that we may want to charge.
The technology behind this novel invention is found in the materials piezoelectric that make up the template. Each step that the person takes causes these materials to press against each other generating an alternating current voltage that can then be stored and used to charge devices. Piezoelectricity is a charge that accumulates in some materials when they are subjected to mechanical stress Angelo Casimiro is very emphatic in clarifying that piezoelectric energy is not something new, but has been present since the mid-17th century, which is a charge that accumulates in some solid materials such as crystals and some ceramics when they are subjected to stress mechanical. What this young man has done is to incorporate this phenomenon of physics, to a very practical use such as being able to charge our mobile devices, which today lack sufficient battery life.Can you imagine being able to go out for a dog walk? , and incidentally charge your cell phone? In this video Angelo explains in detail his project and the altruistic expectations he has for it.
This invention personally seems very promising to me. I can already imagine (like Angelo does) some sports shoes in a few years, with this built-in technology, giving enough power to run devices built into the shoe for measuring sports activities, or as an alternating current source for charging. your cell phone or your wearable gadgets that are becoming so fashionable these days. Here is another video where Angelo tests the mechanics behind the concept of his shoe that generates energy when walking.
