Korean designers Yonggu Do, Jun-se Kim and Eun-ha Seo have found a more conventional use piezoelectricity, in the form of powering our very own tablets and smartphones. Statistically on an average, users press their touch screens over 10,000 times a day. Ingenious system dubbed simply as the Ecopad, where the tablet or any similar device can utilize the piezoelectricity generated by that ‘tapping’ of touch screens. This in effect forgoes the need for those cumbersome adapters (and any power source for that matter), while the device can literally be self powered throughout a period of days. For those who are not acquainted with piezoelectricity – it is the charge which accumulates in certain solid materials (notably crystals, certain ceramics, and biological matter such as bone, DNA and various proteins) in response to applied mechanical strain.
Electricity is made automatically simply by using your ‘ecopad’. currently commercialized tablet PCs and smart phones have a very limited battery life, often not more than a day before having to be recharged. on average, people press their touch screens over 10,000 times a day. the ‘ecopad’ does not require special charging from an adaptor. instead, it generates electricity when a user presses the touch screen due to the nano piezoelectricity .film that is located below the display.
