Researchers at the Technische Universität München (TUM) are
showing the way toward low-cost, industrial-scale manufacturing of a new family
of electronic devices. A leading example is a gas sensor that could be
integrated into food packaging to gauge freshness, or into compact wireless
air-quality monitors. New types of solar cells and flexible transistors are
also in the works, as well as pressure and temperature sensors that could be
built into electronic skin for robotic or bionic applications. All can be made
with carbon nanotubes, sprayed like ink onto flexible plastic sheets or other
substrates.
