A prototype chip able to detect viruses or diseases from a single drop
of blood could soon make easier, and quicker, for doctors to complete
their diagnoses.
In development by a team from the New Jersey Institute of Technology,
the individual devices are spaced six microns apart—the same size as a
single cell. Their structure is based around carbon nano-tubes, which are
crucial in detecting the presence of the cells. Sensors within the
device measure the electrical properties of the blood cells, which
allows the team to detect variances and, eventually, detect sick cells
based on these differences in charges.
An augmented reality system developed for professors allows them to
‘see’ which students are struggling to understand the lesson.
Created by a team at la Universidad Carloss III of Madrid, the system
features a pair of augmented reality glasses worn by the professor
during the lecture. The glasses allow the professor to see symbols above
each student’s head that indicate whether or not they understand the
explanation. To activate the symbols, the students access an app via
their cell phone, enabling the professors gauge the level of
understanding of students too shy to ask questions or request a repeat
of the information.
The Hand Tree is a personal air purifier that, if used by a large
population of people, could also help to clean the air of an entire
city.
Developed by Alexandr Kostin, an Electrolux Design Lab semifinalist, the
Hand Tree concept features a carbon air filter, OLED display and
rechargeable battery. The device can focus air either towards or away
from the body, and the user has the option of adding a scented cartridge
to perfume their personal space. A logo on the touchpad will change
color to indicate the condition of the filter, and a light on the
bioplastic body of the device will indicate the level of pollution in
the surrounding area.
