Abstract
This application provides a haptics structure and a method for fabricating the same, a touch display panel and a touch display device. The haptics structure includes: a base substrate; a platelike deformer on the base substrate; and a strain gauge structure. The deformer includes a first transparent electrode, a second transparent electrode and an electrostrictive material layer between the first transparent electrode and the second transparent electrode, and the electrostrictive material layer is deformed when a voltage is applied between the first transparent electrode and the second transparent electrode. The strain gauge structure is located on a side of the deformer away from the base substrate, and is configured to measure a deformation amount of the deformer.
