Now, persons that are disabled and impaired could say good bye
to awkward crutches and cumbersome wheelchairs! Powered suits are
now coming in style. There are teams of researchers particularly
in Japan are developing 'powered suits' that can support disabled
or elderly individuals in their physical activities. Even individuals,
who are not entirely disabled but have difficulty walking or performing
actions such as standing up or sitting down have a special type
of powered suit. Caregivers also have specially designed suits for
boosting their strength and help them to perform physical tasks,
such as lifting people they care for.
These suits are designed to work by supplementing the wearer's
own physical strength and can be used for everyday activities such
as walking or for rehabilitation. Researchers from both industry
and academia are continually improving their designs with the goal
of making them available for practical use in care and rehabilitation
situations.
Walking aids as a sort of powered suit are now being developed
by a team of researchers in the University of Tsukuba, Japan, led
by Professor Sankai Yoshiyuki. Two main components are featured
in this suit. First, is a metal frame that externally supports the
legs and has motor and sensors, attached, the second component is
a regulator that is carried on the user's back. The sensors affixed
to the surface of the skin instantaneously pick up the faint electrical
signals transmitted from the brain to the muscles, as the wearer
starts to move. Then, it attempts to make the motor's action complement
the motion of the wearer. The weight is not much of a burden to
the user since the heel section is in contact with the ground, though
it's about 23 kilograms.
This suit offers high hopes as a walking aid or rehabilitation
tool for elderly or disabled individuals with reduced physical strength.
This is because this lower-body suit provides support by moving
in a manner that virtually duplicates the wearer's will. The suit
can also perform preprogrammed actions. This feature offers an array
of potential applications, like sports training. In using this suit
in this scenario, muscle signals from an elite athlete would first
be input into the device. By doing this, users could directly experience
the movements of the athlete once they put on the suit. This experience
would help them get more out of their training. For boosting arm
strength, Sankai and his team also plan to develop an upper-body
suit. There are many useful potential applications upper-body suit.
Mitsui and Co., along with a group of small businesses in Ota Ward,
Tokyo was attracted by Sankai and his team's work on the suits.
Tokyo is known as a hive of innovative business activity and the
firms there agreed to cooperate with the University of Tsukuba in
developing the suits to the next level. As of now, many other organizations,
with the academia are involved in developing more types of power
suits.
