Products of
Tomorrow
► Hydrogel
Electrodes Flex
to Fit the
Body's Shapes
Harvard University
has developed flexible,
metal-free electrode
arrays that snugly conform to the body's
myriad shapes, from deep creases of the brain to
fibrous nerves of the heart. This close embrace
allows electrical impulses to be recorded and
stimulated with lower required voltages, enables
their use in hard-to-reach areas of the body, and
minimizes the risk of damage to delicate organs.
The hydrogel-based electrodes take the shape of
whatever tissue they are placed on and open the
door to creation of less invasive, personalized
medical devices.

► Sensors Detect
Inert Gases
Few sensors are available
to detect inert gases.
NASA Ames Research
Center developed a lightweight
sensor that consumes a relatively small
amount of power for detection of inert gases. The
carbon nanotube (CNT)-based sensor detects
inert gases such as argon, oxygen, nitrogen, and
carbon dioxide. The sensor system can provide a
high-sensitivity tool that is very specific for identification
of one or more gas components. The sensors
can be multiplexed to measure current from
multiple CNT arrays for simultaneous detection
of several gas components.

► Anti-Corrosion Compound Protects Steel from the Elements
A flexible, self-healing coating made of sulfur and selenium protects buildings,
bridges, and anything made of steel that sits above or below the water.
Rice University's compound is more dielectric (insulating) than most flexible
materials and more flexible than most dielectrics, making it a good candidate
for components in electronics like bendable cellphones. And when
placed in salt water, the coating was found to be self-healing and could protect steel from the elements.
