Nanopositioners
Researchers at the Peter Grünberg Institute have developed a piezoelectric motor, with a diameter of less than 2.5 millimetres.  Due to the motor’s compact size, scientists can install up to four of these so-called “Koala drives” in a single scanning tunnelling microscope, and thus access samples simultaneously using multiple tips.  This makes it possible, for example, to undertake detailed investigations of charge transport in nanostructures.
