SCALING LAWS

Shrinking changes physics.

If every dimension shrinks by a factor of 10:

L

1 / 10

L²

1 / 100

L³

1 / 1,000

Area and volume do not shrink at the same rate.

SURFACE EFFECTS

Surface area matters more.

◻️ → ▫️ → ·

As an object becomes smaller, its volume decreases faster than its surface area.

That means the surface-area-to-volume ratio increases as size decreases.

Smaller devices are influenced more strongly by surface-related effects.

MICROSCALE PHYSICS

Becomes relatively less significant as structures shrink.

Can remain very useful for sensing and actuation.

MEMS cannot simply be designed as tiny versions of ordinary machines.
