there are patents for charging the mobile by using external charger using piezoelectric material,but i am thinking of having a piezo material inbuilt as we type a lot due to which mechanical pressure is created and with the use of the piezo tech we can charge it to some extent.this would be useful while we are travelling or camping somewhere.
