Ultraflat Haptic Tactile Button for Electronic Device

The goal of this semester project is to study and design such a vibrating key. This report is meant not only to describe a particular vibrating key, but also to serve as a basis for anyone who would want to design one. In this idea, sensing and actuating technologies are described and explained in the first part of the report. The second part is dedicated to the device that was designed for the project. It includes finite elements simulations, electronic schemes, characterization and tests.
