Electrostatic Manipulation of Particle
Abstract:We have been investigating an electrostatic manipulation of a small particle, such as toner and carrier particles. A manipulator consisted of two parallel pin electrodes. When voltage was applied between the electrodes, electrophoresis force generated in nonuniform electrostatic field was applied to the particle near the tip of the electrode. The particle was captured by the application of the voltage and released from the manipulator by turning off the voltage application. It was possible to manipulate not only insulative but also conductive particles. However, if the particle was charged, Coulomb force and adhesion force prevented to release the particle when the voltage was turned off. This condition was apt to take place for small particles, less than 200 μm in diameter. The third electrode was introduced near the dipole electrodes to blow off the particle by the ionic wind and the validity of this system was demonstrated. An uneven electrode system without the additional separation electrode was also developed to release the attached particle independently of the position of the manipulator. Three-dimensional calculation was conducted by the Finite Difference Method and compared to the measured force.

For more than 25 years, NIP has been the leading forum for discussion of advances and new directions in non-impact and digital printing technologies. A comprehensive, industry-wide conference, this meeting includes all aspects of the hardware, materials, software, images, and applications associated with digital printing systems, including drop-on-demand ink jet, wide format ink jet, desktop and continuous ink jet, toner-based electrophotographic printers, production digital printing systems, and thermal printing systems, as well as the engineering capability, optimization, and science involved in these fields.
Since 2005, NIP has been held in conjunction with the Digital Fabrication Conference.
