A Capacitive Information-Based Force-Voltage Responsivity Stabilization Method for Piezoelectric Touch Panels

Piezoelectric force touch panels receive increased attentions in recent years. However, user-induced nonstable force-voltage responsivity limits their successful use in interactive displays. In this work, touch-induced capacitive information is used for estimating contact area and touch angle, which...
