Outline of Final Research Achievements

Modeling of smart materials has been studied aiming at applications for energy harvesting. The novelty of this project is systematic mathematical modeling of smart materials based on control engineering: the obtained model has inputs and outputs and then can be used for simulation or/and designing harvesting devices.
For IPMC sensors, experiments of the derived physics-based voltage sensing model have been conducted. Then, a simplified model of the physical model has been successfully derived. For dielectric elastomer generators, mathematical modeling and optimal design of self-priming circuit has been obtained. For electromagnetic transducers, a new distributed-parameter impedance model and sensor-less parameter estimation method have been proposed.
