In this paper, ultrasonic micromanipulation (UMM) techniques for micron-sized particles in liquid based on the radiation forces of very-high-frequency (VHF) using visual feedback techniques were studied. The possibility of a realization of the new ultrasonic spectroscopy technology in which this study individually selectively evaluates elastic property of the micron-sized particles in liquid was investigated, and the following results and prospects were obtained.1). The Leaky wave transducer using the multistrip coupler was developed to generate the high power density ultrasonic wave beam with the trough in the sound pressure distribution.2). Manipulator using visual feedback and leaky wave transducers was constructed and translation and trapping of the micron-sized sphere were carried out.3). It was clarified of the manipulator in which that the motion of the micron-sized sphere shows the characteristic motion which reflects the elastic property from the experiment, and the new application possibility of this manipulator to the spectroscopy of micron-sized particle was found.4). The new laser ultrasonic micromanipulator (LUMM) in which the ultrasonic wave and laser beam combined complementarily was proposed. The experiment of trapping only the specific particle by the removal of unnecessary particles from large number of particles was carried out successfully.Parts of these results are presented in Inst. of Electrical Engineers of Japan, Inst. of Electronics, lnf. and Commun. Engineering, and IEEE Ultrasonics Symposium. The unpublished results will be presented in near future.
