Abstract: An electronic device includes a pressure providing part, a fluid, and a tactile sensation providing layer. The pressure providing part generates an initial pressure by an electrical signal. The fluid generates a fluidic pressure by the initial pressure in each of active regions partitioned from each other. The tactile sensation providing layer is configured to protrude by the fluidic pressure. The pressure providing layer may include piezoelectric elements mechanically modified by the electrical signal.
