项目摘要

In this study, traveling micromechanisms which should have the most kinds of special features of a micromechanism were trially made and the problems in the process were solved or cleared. (1)Basics of design: Investigating the traveling speeds of natural and artificial traveling things,some natural laws were found out. About the frictional coefficients between flat surfaces pair and radial shaft and bearing pair were investigated and sudden increase at the size below 0.1mm was cleared. The minimum size of the micro mechanisms were analized from the manufacturing accuracy of their parts. (2)Traveling mechanisms : The traveling mechanisms on the ceiling and wall using the surface tension of water were created after the observation of insect. The special feature of the micromechanism on the soft surfaces were cleared. (3)Actuator : For using the water absorptive polymer gel as the actuator, the fundamental equation of the deformation due to electric current was induced and the artificial warm and gel motor were trially made. (4)Supplying energy : Some methods using the electro-magnetic wave, the solar battery, the ultrasonic wave and etc. were investigated. As the method using the circumferantial energy, the balloon model for inside of tube driven by fractuating pressure was made and tested and fundamental study of utilizing the Brown motion energy was done. (5)Measurement of small amount force : Using the vibration impedance change of bimolph piezo-film was investigated and the sensitivity of 10-6[N] was obtained and the method are going to apply to the power measurement of ant now.

本研究试制了应具有最多种微机构特性的行走微机构，并解决或清除了过程中的问题。 (1)设计基础：研究自然和人工移动物体的移动速度，发现一些自然规律。对平面副与径向轴和轴承副之间的摩擦系数进行了研究，消除了尺寸小于0.1mm时的突然增加。微机构的最小尺寸是从其零件的制造精度来分析的。 (2)行走机构：利用水的表面张力在天花板和墙壁上行走的机构是在观察昆虫后制作的。明确了软表面微观机制的特殊性。 (3)驱动器：以吸水性聚合物凝胶为驱动器，推导了电流变形的基本方程，并试制了人工温热和凝胶电机。 (4)供给能源：研究了利用电磁波、太阳能电池、超声波等的一些方法。作为利用圆周能量的方法，建立了破裂压力驱动的管内气球模型并进行了测试，并对布朗运动能量的利用进行了基础研究。 (5)小量力的测量：利用双模压电薄膜的振动阻抗变化进行研究，获得了10-6[N]的灵敏度，该方法现将应用于蚂蚁的功率测量。
