The tremendous development of tactile interface in many customers applications, such as smartphone, leads industrials to study haptic interfaces which allow the user to interact with its environment by the sense of touch. Piezoelectric actuators are commonly used to actuate such interfaces. In this paper, we present a new and innovative technology to integrate collectively commercial piezoceramics into flexible piezoelectric patches able to be integrated on any surface. We glue the flexible patch on a 4×3cm² glass plate to obtain a plug and play interface. A displacement amplitude of 1µm was measured on a Lamb mode at 58.49kHz, using only 20V. A haptic effect was felt by the finger when we modulate at 60Hz the actuation signal, proving the potential of our piezo-in-flex haptic interface.
