A polymer soft actuator is under investigation using a poly urethane elastomer film that bends by means of an applied voltage, which is based on the electrostriction. Bending experiments were performed under different metal electrodes deposited the both sides of the film. Even if the thickness of the both electrodes is the same, the metal of the both electrodes is desirable to be the same to bend more. It is suggested that the balance of the physical properties of the both metal is critical for larger bending.

We fabricated dye-sensitized solar cells including fluorinated gel electrolyte and studied about the relationship between the performance of the solar cells and the aggregation state of TiO 2 nano-particles on electrodes. As for the performance of the cell, the I-V characteristics were measured under irradiation. The combination of TiO 2 nanoparticles with different size plays an important role in bringing unevenness to realize a large surface area, which is critical for the high performance of the cells.
