Above the years smartphones have develop packed with more and more features and however have become easier to operate. Touch screens, millions of applications and high resolution and high quality cameras and displays are all the indignation. Yet all of this has been complemented by an ill-famed reduction in battery life. The old phones that used to need charging after days of usage now need a charge after only a insufficient hours. This has come to be a major irritation especially for those on the road. Happily there may be a simple solution to this problem.

A pool of research teams from the University of Wisconsin-Madison, the University of Minnesota Duluth, and China’s Sun Yat-sen University have come together to plan a piezoelectric covering for smartphones that automatically charge the phone when it proficiencies vibrations (even slight ones). This could principally solve the low battery problem endlessly. Since vibrations are some of the most common incidences in the universe. Everything in the universe moves and henceforth everything vibrates all the time.

The coating is prepared of the piezo-electric polymer, poly viny lidene fluoride. Tiny particles of zinc oxide are deposited on the polymer surface and then removed to leave spaces that make the material squishy in its place of unbending. The dynamic energy of the vibrations permits the polymer to enlarge and contract and this produces a current that unremittingly charges the phone.

The idea looks almost too simple in theory and one wonders why no one ever supposed of it before. As with every truly great invention in any pitch of science, perhaps it’s always gazing you in the face.
