Title: Matthieu Rupin: Innovator in Piezoelectric Technology
Introduction
Matthieu Rupin is a notable inventor based in Saint Martin d'Hères, France. He has made significant contributions to the field of electromechanical actuators, particularly in the area of piezoelectric technology. With a total of 7 patents to his name, Rupin's work has advanced the capabilities of haptic feedback and vibration control.
Latest Patents
One of his latest patents is focused on piezoelectric actuators with increased deformation. This invention relates to an electromechanical actuator that includes at least one drive element connected to a source of AC voltage. This setup produces a deformation of the drive element, while a plate amplifies the amplitude of the vibration transmitted to a substrate. The design ensures that one face of the plate is rigidly fixed to the drive element, while the opposite face is connected to the substrate via an actuation lug.
Another significant patent involves a method for creating a haptic effect using focused ultrasound waves. This method utilizes at least two piezoelectric actuators that emit ultrasonic frequency control signals. These signals create vibrations at the surface of a solid, generating a haptic effect at a target point. The control signals are calculated based on the distance between each actuator and the target point, enhancing the overall haptic experience.
