Australian researchers seem to want to use the keyboard to distribute electricity from a finger pressure. Armed with that ability, laptop or smartphone, or mobile phone users just need to type a letter or number on the keyboard to make light batteries last longer.
charging batteries for smartphone only uses finger pressure
A number of researchers at the Royal Melbourne Institute of Technology are developing technologies that allow certain materials generate electricity only under pressure. The idea is to put the piezoelectric film under the keyboard or the keypad to generate electricity whenever the device is pressed.
The technology is still the 'baby' and now can only be used to extend battery burn time by 10%. Initially, the technology was developed to take advantage of physiological processes in the human body. For example, making the blood pressure as a source of energy.
However, the rapid development of mobile phones and computer touch screen makes the future of technology that can generate electricity from the finger pressure is questionable. Moreover, if the emergence of three more years.
