Aussie breakthrough can recharge devices by typing
Piezoelectrics is the ability to turn pressure into electrical energy.
In this case the pressure of pressing a key would generate a charge to keep the battery topped up.
“The power of piezoelectrics could be integrated into running shoes to charge 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,” Dr Madhu Bhaskaran, lead co-author said.
“The concept of energy harvesting using piezoelectric nanomaterials has been demonstrated but the realisation of these structures can be complex and they are poorly suited to mass fabrication.
“Our study focused on thin film coatings because we believe they hold the only practical possibility of integrating piezoelectrics into existing electronic technology.”
Imagine not having to recharge your laptop or mobile and just the pressure of typing on the keyboard or the screen was all that you needed to power the device and recharge its battery.
“With the drive for alternative energy solutions, we need to find more efficient ways to power microchips, which are the building blocks of everyday technology like the smarter phone or faster computer,” Dr Bhaskaran said.
“The next key challenge will be amplifying the electrical energy generated by the piezoelectric materials to enable them to be integrated into low-cost, compact structures.”
