accompanying documentation and software
openly available on GitHub. The
team hopes this will attract more enthusiasts
involved in brain-computer interface
development, giving an impetus to support
an rehabilitation system development,
cognitive research, and pushing
the geek community to come up with
new futuristic gizmos.

used for research, diagnostics, or gadgetry.
The problem with the existing
systems used in labs and hospitals is
that they are bulky, expensive, or both.
And even then, the number of electrodes
is limited, resulting in moderate
signal quality. Amateur devices tend to
be more affordable, but with even poorer
sensitivity.
To fill that gap, researchers from
South Ural State University, North
Carolina State University, and Brainflow
- led by electronic research engineer
Ildar Rakhmatulin and Skoltech neuroscientist
Prof. Mikhail Lebedev - created
a device that can be built for just
$350, compared with the $1,000 or more
needed for currently available analogs.
Besides being less expensive, the new
electroencephalographer has as many as
24 electrodes or more.
Importantly, it also provides researchgrade
signal quality. At half a centimeter
in diameter (about 1
unit
⁄5
in.), the processing
is compact enough to be worn
throughout the day or during the night.
The entire device weighs about 150 g
(about 5 oz).
The researchers have made the instructions
for building the device and the
" The more convenient and affordable
such devices become, the more
chances there are this would drive the
home lab movement, with some of the
research on brain-computer interfaces
migrating from large science centers
to small-scale amateur projects, "
Lebedev says.
" Or we could see people with limited
mobility using do-it-yourself interfaces to
train, say, a smartphone-based system that
would electrically stimulate a biceps to
flex the arm at the elbow, " the researcher
says. " That works on someone who has
lost control over their arm due to spinal
cord trauma or a stroke, where the commands
are still generated in the brain -
they just don't reach the limb, and that's
where our little brain-computer interfacing
comes in. "
According to the team, such interfaces
could also help patients with
epilepsy by detecting telltale brain activity
patterns that indicate when a seizure
is imminent, so they can prepare by
lying down comfortably in a safe space
or attempting to suppress the seizure via
electrical stimulation.

Researchers Develop Soft, Stretchable Thermometer
The self-powered sensor
can be integrated into soft
robots or smart clothing.
Harvard SEAS
Cambridge, MA
The next generation of soft robotics,
smart clothing, and biocompatible medical
devices are going to need integrated
soft sensors that can stretch and twist with
the device or wearer. The challenge: most
of the components used in traditional
sensing are rigid.
Now, researchers at the Harvard John A.
Paulson School of Engineering and
Applied Sciences (SEAS) have developed
a soft, stretchable, self-powered ther34
