What is MEMS? MEMS: Micro Electro Mechanical Systems

Definition: systems in micro scale (10-6~10-3 m) that combine electrical and mechanical components and are fabricated using semiconductor fabrication techniques.

MEMS integrates functions of sensing, actuation, computation, control, communication, power, etc.

Typical MEMS devices: MEMS pressure sensor, accelerometer, microgyroscope, micromotor, resonator, valve, gear, micromirror, optical switch, microneedle, RF capacitor, lab-on-chip, etc.

NEMS: Nano Electro Mechanical Systems (10-9~10-6 m).

Nanotechnology Nanotechnology: a field of applied science and technology

whose unifying theme is the understanding and control of matter on the atomic and molecular scale, normally 1 to 100 nanometers, and the fabrication of devices within that size range.

Nanotechnology is a general-purpose technology which will have significant impact on almost all industries and all areas of society. It can offer better built, longer lasting, cleanser, safer and smarter products for home, communications, medicine, transportation, agriculture and many other fields.
