Cell phones that never need charging

At Texas A&M University, Dr. Tahir Cagin in ChemE made a significant discovery in the area of power harvesting. He showed that utilizing piezoelectric materials on the nanoscale enables energy harvesting from sound waves. Cagin et al. found that a specific type of piezoelectric material can convert energy at a 100 percent increase when manufactured around 21 nm in thickness. When the material is constructed thicker or thinner than this, it shows a significant decrease in energy converting capability. The findings were recently published in Physical Review B. This technology could enable self-powered devices within many different applications like cell phones, mp3 players, and portable computers. Read this and the 7 other very interesting new below. How cool is that!?
