15 Year Old Invents Device That Generates Electricity While You Walk


15-year-old Angelo Casimiro from the Philippines recently made international news with a new invention that generates electricity in a very new and interesting way.

The invention is a shoe insole that harnesses electricity every time that the person wearing the shoe takes a step. Angelo constructed his device using piezoelectric materials, which actually generate an alternating current voltage every time they are squeezed.

According to a blog post made by the teenager, “Piezoelectricity was present ever since mid-18th century. Piezoelectricity is the electric charge that accumulates in certain solid materials (such as crystals, certain ceramics in response to applied mechanical stress.”

Young Angelo has been working hard developing this idea for the past 4 years, since he was 11 years old.  Now that he believes he has perfected his invention, he is prepared to share it with the world.  He started by entering the project into this year’s Google’s Science Fair, where he has become a regional finalist.
