Can you ever imagine laptops getting charged by your fingers. A research has discovered a technique that can channelize the energy from fingers tapping on a computer keyboard to recharging the computer itself, as reported by the Gizmag.
Dr. Madhu Bhaskaran and her colleagues from RMIT University in Melbourne for the first time managed to accurately measure the voltage and current generation for nanoscale piezoelectric thin films.
"The power of piezoelectrics could be integrated into the running shoes to charging mobile phones, enable laptops to be powered through typing or even used to convert blood pressure into a power source for pacemakers - essentially creating an everlasting battery," Madhu told Gizmag.
She also added that it was in the 19th century Piezoelectricity was first discovered, but the research on thin films and its power to harness and use the electricity is relatively new. The science of converting pressure into electrical energy, popularly known as, piezoelectric has already proved its diligence in several daily life gizmos - mobile phone is the most common one.
