- Title:Self-Alignment of Micro-Spheres Base on Dielectrophoresis
- Ho Won Yoon, Kyung Hwan Yang, and MunPyo Hong (Korea Univ., Korea)
Abstract: We have been researching on individual micro-sphere alignment technology in order to fabricate conductor coated polymer ball (CCPB) based e-paper. Using a positive dielectrophoretic force (p-DEP), we were able to demonstrate alignment of micro-spheres in 3x3 array. Although we expected p-DEP to be induced on CCPB in any frequency range due to the permittivity and conductivity of our colloid, self-alignment was presented under 1 kHz. In low frequency range, unnecessary remaining CCPB was observed none the less p-DEP was confined to a center of dot-ring pattern. We assumed it due to very strong Coulomb force and adhesion. We have expanded its size to 1096x352 array and self-alignment experiment on a large scale is on proceeding.
