Products of
Tomorrow
► Woven Nanotube Fibers Turn Heat into Power
Rice University has made custom nanotube fibers for a fiber-enhanced, flexible
cotton fabric that turns heat into enough energy to power an LED. With further
development, such materials could become building blocks for fiber and textile
electronics and energy harvesting. The same nanotube fibers could also be used as
heat sinks to actively cool sensitive electronics with high efficiency. With the new
fabric, if one side of the thermoelectric material is hotter than the other, it produces
energy. The heat can come from the Sun or other devices. Conversely, adding energy can prompt the material
to cool the hotter side.

Creates
System
NASA's Johnson
Space Center developed
a suite of RFIDbased
technologies fo -
cused on improving communication of an RFID
reader with a greater number of RFID tags in open
and enclosed areas. The Agile RFID Antenna
System can expand these boundaries by integrating
an inexpensive frequency multiplexer to the RFID
reader antennas, which permits new methods of
localization, allows greater antenna functionality
with fewer reader RF ports, and provides improved
read accuracy and/or range. Applications include
manufacturing/assembly line tracking, industrial
transportation and logistics, and healthcare.

Antimicrobial
Fabric
North Carolina
State University used liquid gallium to create an
antiviral and antimicrobial coating and tested it on
a range of fabrics including facemasks. The coating
adhered more strongly to fabric than some conventional
metal coatings and eradicated 99% of several
common pathogens within five minutes. The coatings
were tested against human influenza (H1N1)
and coronavirus (which is in the same family as
SARS-CoV-2). The coatings eradicated the viruses
after five minutes. It could also work with metals
other than copper, such as silver.
