A flexible electronic device that can be folded and unfolded in three different dimensions is disclosed. The present disclosure provides a flexible electronic device comprising: a flexible substrate comprising a predetermined bending area, the predetermined bending area having a first surface and a second surface opposite the first surface and at least one piezoelectric element arranged on the first surface of the predetermined bending area and capable of receiving a first electric signal, wherein the at least one piezoelectric element can contract or expand in response to the received electric signal so as to deform the flexible substrate in a first deformation direction.本發明揭示一種可以三維度折疊的可撓式電子裝置,可以任意對折縮小並展開。本發明提供一種可撓式電子裝置,其包含一可撓基板,該可撓基板包含一預定彎折區,該預定彎折區具有一第一表面及與該第一表面相對的一第二表面;及至少一第一壓電元件,其位於該預定彎折區的該第一表面上,並可以接收一第一電信號,其中該至少一第一壓電元件可以回應於所接收的該電信號而收縮或伸張,使該可撓基板以一第一形變方向形變。41‧‧‧第一狀態42‧‧‧第二狀態43‧‧‧第三狀態
