MEMS (Microelectromechanical Systems)

Microelectromechanical Systems (MEMS) is a technology platform that integrates miniaturized mechanical structures, sensors, actuators, and electronic circuits onto a single silicon substrate using photolithographic fabrication processes.

Overview

Operating at characteristic dimensions from one to hundreds of micrometers, MEMS devices interact with physical phenomena — motion, pressure, temperature, chemical concentration, and light — with exceptional precision. Fabrication techniques including bulk micromachining, surface micromachining, and LIGA (lithography, electroplating, and molding) offer distinct trade-offs between structural complexity and production cost.

Why it matters

MEMS dissolved the traditional boundary between sensing the physical world and computing about it, enabling the accelerometers in smartphones, pressure sensors in automotive airbags, microphones in hearing aids, and micromirrors in digital projectors — technologies so thoroughly embedded in modern infrastructure that their absence would fundamentally alter medicine, transportation, and communications. The platform's ability to mass-produce physical intelligence at chip scale represents a major advance in how humans instrument and interact with the world.
