Module 1: MEMS Overview

2025?m

The dominant force scaling advantage in MEMS at the micro-scale is:

(i) Gravity
(ii) Inertia
(iii) Surface Tension
(iv) Magnetic Force

Answer: (iii) Surface Tension

At the microscale, surface-area-to-volume ratio becomes very large. As a result, surface-related forces such as surface tension and adhesion become much more significant compared with body forces such as gravity.
