    The following basic research is being carried out in our laboratory on electromechanics of particles, because it is a basis of digital printing technology: (1) Experimental, numerical, and theoretical investigations have been conducted on statics of magnetic bead chain in magnetic filed. Chains formed on a solenoid coil were observed and chain lengths and slant angles were measured. Stable configurations of chains were theoretically discussed in point of potential energy minimization. Numerical simulations were also performed using the Distinct Element Method considering magnetic interaction forces and the results were compared with the experimental results. (2) Dynamics of the magnetic bead chain has been also investigated. Chains were vibrated by the sine-wave excitation and an impact testing methods and the resonance frequency was deduced. Experimental results were confirmed by the theoretical consideration and the numerical calculation with the Distinct Element Method. (3) A technique to transport dielectric particles is developed utilizing traveling electrostatic field. A fundamental study is being carried out.
