| Research Abstract |
The objective of this research is (1) modeling for design and control on the basis of ionic migration (modeling of distributed internal stress caused by ionic migration by electric field, motion and diffusion of water molecules, swelling and contraction by water content, electrostatic force, lateral strain, conformation change), and (2) design of electric field patterns (design of electric field patterns and control of internal stress distribution).
Research results are summarized as below.
1) Electrochemical modeling of migration of sodium ions and motion and diffusion of water
2) Modeling of momentum effect, swelling and contraction by water, electrostatic force, and conformation change
3) Modeling of visco-elasticity by FEM
4) Modeling of lateral strain caused by deviation of sulfonic ions
5) Stable numerical solution of theoretical equations using method of finite difference
6) Development of simulation programs and relation with FEM software
7) Identification of viscoelastic parameters and swelling ratio by experiments
8) Verification by comparison of simulation results with experimental results (qualitative effectiveness was verified)
9) Design of electric field patterns and electrode locations for traveling wave on PVA-DMSO gel actuator
10) Development of masking technique for electrode pattern fabrication on ICPF surface
11) Experimental verification of traveling wave by control of internal stress distribution
