From 3-D printers repairing bones
and making pizzas to newer drugs for cancer, science seems to be taking a giant
leap forward in just a short span of time.
Now it's time to welcome the
newest invention- artificial skin which can sense humidity, touch and
A team of researchers at the
Technion-Israel Institute of Technology has successfully created a new sensor,
which could render artificial, lab-grown skin as useful as real skin, complete
with the ability to sense touch, humidity and temperature differences.
This new 'skin,' called the
skin, or electronic skin
, will prove to be of great use to patients having
The sensor, made up of tiny gold
particles and a special kind of resin, will help it sense different stimuli
when attached to artificial skin.
Unlike other inventions, this
very sensor "can simultaneously sense touch, humidity, and temperature, as
real skin can do," team leader of the research, Professor Hossam Haick,
This new system "is at least
10 times more sensitive in touch than the currently existing touch-based e-skin
systems," he added.
Over the years, flexible sensors
have been a major topic of interest for scientists. However, the presence of
some major real-time hurdles has hampered their development.
The flexible sensors, for
application in the real-world, need to be able to detect different measurements
(pressure, temperature, humidity etc), run on low voltage and have a low cost.
Thankfully, this new sensor,
manages to achieve all of that.
Combining the intelligent use of
gold nanoparticles on a substrate, the sensor can detect a large range of
pressures, up to tens of grams.
"Indeed, the development of the artificial skin
as biosensor by Professor Haick and his team is another breakthrough that puts
nanotechnology at the front of the diagnostic era," Dr Nir Peled, head of
the Thoracic Cancer Research and Detection Center at Israel's Sheba Medical
