Johns Hopkins materials scientist Michaely Yu and his team claim to have invented a material which could allow for piezoelectic sound devices to be placed in areas previously thought to be too challenging.
The invention provides for a resin polymer which possesses piezoelectric properties usually found only in very heavy, brittle materials. If the early findings hold up, the flexible material and could be used to produce a coating which could create speakers embedded into wallpaper or even speakers that could be folded in two.
