Your itchy fingers can produce electricity!!
Piezoelectric effect is the phenomenon by which certain crystals such as quartz, rochelle salt, etc. produce electricity or electric polarity when subject to mechanical stress, or alternatively, when such crystals are subject to an electric field they produce mechanical vibrations.
You can wipe the triumphant smile on your face for getting the definition right. This is neither high school physics nor are you getting rewarded for getting the definition right.
What if you could charge mobile phones, laptops, and other electronic devices just by key strokes using the piezoelectric effect?
Dr. Madhu Bhaskaran and her team at the RMIT University in Melbourne have now been able to measure the voltage and current generation for nanoscale piezo-electric thin films.
While speaking to the Gizmag magazine, Dr. Madhu stated that it was possible to utilize piezoelectrics in shoes, mobile phones, laptops, and even use human blood pressure to power pacemakers.
She also said that even though piezoelectricity was discovered in the 19th Century, there has not been sufficient research on the potential of piezoelectrics.
When will devices powered by piezoelectric cells come to the market? We don’t know yet, but imagine the amount of power that can be generated from tens of thousands of keystrokes in an I.T. Park or a shopping plaza covering an area of 2000 square feet running on the power of foot falls. That’s piezoelectricity for you.
