Development of a CNC Surface Vibration Scanning System

The EPFL – LAI is investigating novel haptic technologies for rendering rich vibrotactile feedback in digital musical interfaces. The main objective is to develop an interactive surface that is able to render a multi-touch vibrotactile stimulus using piezoelectric actuators and wave focusing strategies. Scanning the surface to obtain the peaks and displacement is key during the development and characterization of the whole system. The goal of this project is to develop a system that can measure small vibrations (in the order of 2 – 20 um) that are produced in the different points of a surface, when different waveforms are transmitted to the surface using piezoelectric transducers. This project will allow you to get hands-on experience with the software and hardware integration of a 3-axis CNC table, a waveform generator, a laser Doppler vibrometer, and an oscilloscope.
