Abstract

3-dimensional touch sensing and long battery lifetime are two desired attributes in interactive displays. By employing piezoelectric material and rectifier circuitry related technique, force touch induced charges are used for both force strength detection and energy harvesting, achieving 3dimensional touch sensing and extended battery lifetime at the same time for interactive displays.
