Abstract
A flexible touch panel apparatus includes a series of first electrodes extending along a first direction, at least one second electrode extending along a second direction and defining a bending axis of the flexible touch panel. An elastomeric layer is located between the series of first electrodes at least second electrode. A series of third electrodes are extending along the second direction parallel to the bending axis, and an insulator layer is located between at least one second electrode and the series of third electrodes. At least one second electrode is capacitively coupled to at least one of the series of first electrodes for bend sensing in the flexible touch panel along the bending axis, and the third electrodes are capacitively coupled to the first electrodes for touch sensing on the flexible touch panel.
