This Touchy Tech Could Abolish Wall Warts

Here’s how you may soon charge your phone by tapping on it rather than plugging it in. Thanks, science! Australian researchers have made a breakthrough in thin-film piezoelectric technology, working out a way to turn the chunky piezo electric tech we’re already familiar with into super-thin layers that are actually much more useful. If your eyes glaze over at the merest mention of physics then at least read this: The tech could abolish wall wart power plugs forever.
