MEMS are minitiarised to microscopic level and therefore have :

  • A.Low sensitivity
  • B.Large dynamic range
  • C.Very low frequency response
  • D.High mechanical strength

Answer: B

The keyed property is a large dynamic range.

Because MEMS sensors have very small moving masses, they combine high sensitivity with high resonant frequencies, and they can respond to signals over a wide range of amplitudes, from very small to large, before saturating, which is described as a large dynamic range.

Low sensitivity is the opposite of what miniaturisation gives. Their small mass gives a high, not very low, frequency response. High mechanical strength is not what follows from miniaturisation, since tiny structures are fragile and must be packaged to protect them.
