Abstract
A piezoelectric touching sensor includes a lower substrate, a lower electrode layer, a piezoelectric material layer, at least one upper electrode layer, and an upper substrate. The lower electrode layer is disposed over the lower substrate. The piezoelectric material layer is disposed over the lower electrode layer. The upper electrode layer is disposed over the piezoelectric material layer, respectively at a preset position. The upper substrate is disposed over the upper electrode layer. At least one of the lower substrate, the piezoelectric material layer and the upper substrate is serving as a pressure increasing layer. At least one protruding structure layer is disposed between the pressure increasing layer and the lower electrode layer, or the upper electrode layer, so as to reduce a pressure-applying area and increase the sensibility for an external stress applied on the piezoelectric material layer. When the external stress is applied to the upper electrode layer, a signal can be respectively sensed via the piezoelectric material layer.
