This column presents technologies that have
applications in commercial areas, possibly creating the
products of tomorrow. To learn more about each
technology, see the contact information provided for
that innovation.
Products of
Tomorrow
Electronic
Textiles from Conductive Cellulose Thread
Chalmers University of Technology (Sweden) developed a thread made of conductive cellulose that can be used to create built-in electronics in non-toxic, renewable,
and natural materials. Sewing the electrically conductive cellulose threads into a fabric
using a standard household sewing machine, the researchers produced a thermoelectric textile that produces a small amount of electricity when it is heated on one side; for example, by a person's
body heat. At a temperature difference of 37 C, the textile can generate around 0.2 microwatts of electricity.
Applications include regulating, monitoring, and measuring various health metrics.

Light-Emitting
Tattoo
University College
London (UK) developed a temporary tattoo that uses organic
light-emitting diodes (OLEDs) and is applied in the
same way as water-transfer tattoos. The OLEDs are
fabricated onto temporary tattoo paper and transferred to a new surface by being pressed onto it and
dabbed with water. It could be combined with other
tattoo electronics to emit light when an athlete is
dehydrated or when the wearer has been in the Sun
too long. OLEDs could be tattooed on packaging
or fruit to signal when a product has passed its expiration date or will soon become inedible.

Non-Destructive
Testing of
Composites
NASA's Langley Research Center developed a Non-Destructive Testing (NDT) method for identifying and
characterizing hidden damage in composite materials. The technique requires only single-sided access to the test specimen and uses trapped energy
analysis to detect and characterize damage that was
previously obscured. The method uses 3D custom
ultrasonic simulation tools to identify multilayer
delamination damage. Understanding the extent
of composite damage is essential for repair and
replacement decisions and could prevent catastrophic in-service failure.
