Abstract
Embodiments of the disclosure provide a touch panel and a touch device. The touch panel includes: a touch structure; a tactile sensor stacked with the touch structure and configured to generate a standing wave on a surface of the touch panel during operation to realize tactile reproduction; and a first electrode layer located between the touch structure and the tactile sensor, where the first electrode layer is insulated from the tactile sensor and the touch structure, and the first electrode layer is grounded; and a base substrate located between the touch structure and the tactile sensor.
