近日,英国伯明翰大学宣布,该校研究人员开发出一种只有几毫米大小的微型发动机。据了解,该发动机提供的能量是普通电池的300倍,驱动装置比电池驱动装置工作时间长,只要给这种发动机补充一次燃料,它就能连续工作几个月甚至一两年,不仅免去了工作人员经常换电池或电池充电的麻烦, Recently, the University of Birmingham announced that researchers at the university have developed a micro-engine that is only a few millimeters in size. It is understood that the engine to provide energy 300 times the normal battery, the drive device than the battery-operated device for a long time, as long as the engine to add a fuel, it can work continuously for several months or even a year or two, not only removed The staff often for the battery or battery charging trouble,
