At the Center for Research in Advanced Materials (CIMAV), scientists decided to “capture” the energy produced by people walking. They designed a pill-shaped cylinder adapted to a shoe in order to store the mechanical-vibrational energy the person generates when walking.

The captured energy was used to recharge a clock with triple A batteries. The prototype designed by CIMAV in Chihuahua, in the north of Mexico, adapted the device, which has a diameter of two inches and a thickness of three millimeters, to the sole of a shoe.
