| Outline of Final Research Achievements |
For microparticle manipulation using dielectrophoresis (DEP) phenomenon, precise model of the microparticle is required. In medium, the electrical double layer is formed on the surface of the microparticle. The microparticle model including the electrical double layer can explain the measured frequency dependence of DEP for the polystyrene microparticles and so on. In addition, to avoid heating from the DEP chip, a circuit with different frequencies for the DEP and AC wireless power transfer has been developed. It has on-chip oscillator for the adequate low-frequency DEP driving signal, and improves the wireless power transfer with higher frequency.
