Original abstract
This paper deals with a metamaterial for sensing purposes under Industry 4.0 applications. The presented of metamaterial is based on an auxetic structure which is made by Direct Metal Laser Sintering technology. The stain steel auxetic structure could integrate smart material elements or systems for electromechanical conversions. The proposed concept of metamaterial uses the auxetic structure with piezoelectric elements or stacks to transduce external load of structure into electric signal. The auxetic structure could provide uniform mechanical load on several smart piezoelectric elements in middle layers due to negative Poisson ration. The paper presents a FEM simulation of this concept and analysis of coupled electromechanical system under harmonic excitation. Deformation of auxetic structure with piezoceramic PZT plates is presented and the voltage response is analyzed. The assembly of metamaterial system with piezoelectric PVDF in case of soft application is also presented and it will be tested under future development.
