Researchers
at the Korea Advanced Institute of Science and Technology (KAIST) have
developed a highly sensitive exhaled-breath sensor, using tin dioxide (SnO2)
fibers assembled from thin, wrinkled SnO2 nanotubes.
These
metal-oxide nanofiber-based chemiresistive gas sensors allow for portable
real-time breath tests that could be available on smart phones or tablets in
the near future.
They
sensors allow for diagnosing serious diseases such as diabetes or lung cancer
quickly and effectively by simply breathing into a small nanofiber breathing
sensor, mounted on a phone or other device.
“The sensor
technology can be compatible with various types of smartphones, portable
electronic gadgets, and medical devices,” he added. “We believe that there can
be many ways to incorporate our technology based on particular needs of
industries, not just in the medical device field, such as detecting hazardous
chemicals or gas at manufacturing factories.”
