Memory card having display function using piezoelectric effect and method thereof
摘要:
A memory card includes a piezoelectric material and a display unit. The piezoelectric material generates a voltage from external pressure applied thereon, and the display unit displays information using the generated voltage. Thus, information is displayed on the memory card at the discretion of the user pressing the piezoelectric material without using any additional equipment. Also, few components are added to the memory card for such a display function such that the small form of the memory card is retained.
