Motion Control of Protozoa by Electrical Field (1st Report, Basic Reaction Property for D. C. Electrical Field and Developement of the Automatic Control Method)

摘要

This study investigates the possibility whether protozoa can be treated as a living micro manipulator/actuator or not. Motion control of protozoa is made by using the negative galvano- taxis. First, basic property test for DC electric held showed that Paramecium can control its motion by the electrical potential gradient. By using the 8 direction carbon electrode pool (electrode distance: 4 mm, thickness: 0.2 mm), operator can control the Paramecium to the aiming direction. Automatic motion control of protozoa was also achieved by using the image processing technology and fuzzy control method. These facts show that protozoa is able to use at a micro manipulator.
