Modeling is an important research activity which allows transferring the properties of materials to the device scale. Together with simulations, modeling is used as a design tool. In a broad perspective, different approaches are used to model complex systems built on different components, e.g. elastomers, piezoelectric films, electronic devices… Different disciplines and knowledge are at the core of these approaches, i.e. physics, solids mechanics and electronics. We have acquired some skills on modeling:
The macroscopic behavior of materials and structures basing on materials constitutive equations
Piezoelectric films working in thickness and bending modes
The structure of an electronic skin, to interpret tactile data from a sensor array beneath a cover layer (general method, provided that sensors give information about the T33 stress component)
Integrated nonlinear photonic material and structures for optical signal processing
The first three activities are carried on in collaboration with the Materials Engineering group (Prof. M. Capurro), Department of Civil, Chemical and Environmental Engineering, University of Genoa
