Nanogenerators—Georgia Institute of Technology
These nanometer-scale generators produce continuous direct-current electricity by harvesting mechanical energy from such environmental sources as ultrasonic waves, mechanical vibration, or blood flow. The devices are based on arrays of vertically aligned zinc-oxide nanowires that move inside a novel zig-zag plate electrode. They take advantage of the unique coupled piezoelectric and semiconducting properties of the zinc-oxide nanostructures.

Nano Imprint Lithography (NIL) Equipment, NPS300—SUSS MicroTec Lithography GmbH
NIL exists in two methods—UV-NIL and hot embossing. Both methods consist of printing a mold/stamp with nm-features onto a polymer, thus transferring the stamp pattern into that material. Curing of the polymer is then performed with either UV light or temperature. The uniqueness of the NPS300 equipment is in the fact that it can handle both technologies without any tradeoffs or shortened changeover capabilities.

Nano Indenter G200—MTS Systems Corp.
Nano Indenter G200 is a next generation nanomechanical testing system.
