Abstract
An apparatus and associated methods utilize a flexible touch panel having a layer of piezoelectric material arranged between a number of first electrodes and at least one second electrode and a device connected to the first electrodes and configured to determine a bending state of the touch panel based on one or more radii of curvature of the touch panel from signals received from one or more of the first electrodes. A touch location for one or more user interactions is determined from signals received from the one or more of the first electrodes. An electronic device including the apparatus may switch between operating modes based on the bending state of the touch panel. A non-transitory computer readable medium may store computer programs implementing the methods for determining the bending state of the touch panel, switching the device between modes based on the bending state and determining a touch location.
