(B)MICROMACHINES
Also critical for future mechatronic systems is micromachining technology.Techniques exist for producing functional devices or mechanical parts smaller in diameter than a human hair.This size allows placing sensors directly on Ics and using gears,motors,and a variety of actuators in micromachines or microrobots. A recent micromachines technology impact report from Frost & Sullivan (New York) defines micromachinery as that consisting of gears,shafts, and other components that function in the same general way as fullscale machinery. One example is the electric motor developed at the Berkeley Sensor and Actuator Center at the University of California (Berkeley). The rotor of the device measures 60 um,whereas a human hair measures 70～100um.
This becomes more apparent as manufacturers explore use of micromachines that work in the world of individual atoms.One atom is 1/10,000 the size of a bacterium. A bacterium is 1/10,000 the size of a mosquito. Elements the size of bacteria are in the microworld, measured in microns.
The laws of physics give micromachines some advantages over their full-scale cousins.Microrobots,for example,will have capability to move only a few micrometers at a time.Therefore,they will be significantly more accurate than their full-scale cousins

Answer 1

微型机械
对于未来的机电系统同样重要的是显微机械加工技术。现有的这种技术已经能制造出来小于人类头发直径的功能性部件和机械零件。这种尺寸的加工技术使得我们可以直接将传感器置于芯片上，或者将齿轮、电机或各式执行器装于微型机械和微型机器人上。在最近一次由Frost & Sullivan公司发布的微型机械技术的影响报告中将微型机械定义为“由微型齿轮，微型轴和其他微型部件组成的，但与原尺寸机械以同样方式运行”。以加州大学的伯克利传感器与执行器研究中心发明的微型电动机为例，该装置中的转子仅为60微米——人类头发的直径一般在70微米到100微米。
而现在越来越多的制造者正在寻求制造出能在独立的原子中工作的微型机械。原子的大小只有细菌的万分之一，而细菌的大小又只有蚊子的万分之一。细菌层级的尺寸就属于微观世界，以微米作为度量单位。
物理法则的存在使得微型机械相比其全尺寸的兄弟具有了许多优势。以微型机器人为例，它有能力可以一次只移动几微米。因此，很明显它将比它的全尺寸兄弟更精确。
