For those who have always been worried about the walls which had ears have something more to worry about for ‘walls that can talk’ are finally here. This is again a concept which once materialize will turn all your walls into speakers bloating out your favourite music. This one is going to be the most challenging innovation in the world of speakers leaving behind the shell series speakers or the Ferrari inspired speakers.

Now materials scientist Michael Yu at Johns Hopkins University has come up with this new material which will allow piezoelectric sound devices to be fixed precisely any where inside the most inaccessible places.

Piezoelectric devices are found in microphones and speakers that move in response to voltage, or create voltage from movement.

Earlier found only inside very heavy, brittle materials the polymer with piezoelectic properties will be used as a coating that will be flexible enough to create speakers under your wall paper. Not just this, the new material will also open up possibilities to make innovative inventions like foldable speakers and more.
