Nanotechnology

The term was first proposed by K.Eric Drexler in the 1970's.

A nanometer is one billionth of ameter.

It involves the manipulation of thestructure of matter atom-by-atom.

It is currently undergoing extensivedevelopment.

It has not yet yielded significantlyuseful commercial products.

Nanomanufacturing

It is now quite accepted as was theidea of flying to the Moon in the prespace age year of 1950.

It will use nanomachines to buildstructures, features, devices,systems, as well as othernanomachines.

Most research predicts that within 20to 30 years nanomanufacturing willbecome a reality.

What are Smart Materials?

Senses a stimulus (eyes).

Takes an intelligent decision

(brain). Through electronic feedback it

takes corrective/preventivemeasures to avoid catastrophicsituations (arm).
