Abstract

The paper is dedicated to analysis, practical exploitation of sonotrode, whose fundament is multilayer actuator in experiments of mechanical hot imprint. The goal is to compare the quality of microstructures, created by using vibration based on multilayer actuator. Numerical modelling and experimental analysis is performed in order to find resonant frequency of the sonotrode. Having operating frequency, sonotrode applied in mechanical hot imprint process. Microstructures are created on the surface of polycarbonate; the only process variable is vibration. Two types of microstructure quality measurements are performed: measurement of diffraction efficiency, optical microscopy in order to examine quality of replica
