尽管光或味觉等传感器无法感知辐射，但科学家手中的精密仪器可以轻易发觉即使是最轻微的辐射。
Although radiation cannot be detected by the senses (sight, smell, etc.), it is easily detected by scientists with sophisticated instruments that can detect even the smallest levels of radiation.
这种装置利用多种传感器感知出正在行驶路段的轮廓并在驾驶员偏离车道是响起警报。
It USES multiple sensors to set up a profile of the way someone drives and sounds the alarm if he departs from it.
传感器内部是由碳纳米管制成的微型“弹簧”——非常细小，像头发丝一样——能够感知不同的压力，小到轻轻地捏一下，大到相当于两头大象站在顶上。
Inside are tiny "springs" made of carbon nanotubes - minuscule hair-like filaments - that can "sense" pressure from a slight pinch up to the equivalent of two elephants stepping on top of the sensor.
