What is piezoelectric technology?
Recently the students of ‘American University of Sharjah’ have discovered the instrument which produce electricity from the sounds. They changed the energy in sounds to electricity with the help of piezoelectric technology. This instrument identifies the sounds which are not audible to human being. For example if we put this instrument at the speed breakers then the sounds of the vehicles can change into the electricity and with this electricity we can light the street lamps. This experiment is in early stage. These types of experiments save the energy sources and save the environment. Let we hope that this type of experiments will be successful.
