| Summary: | For an assistive device to be usable in carrying out
activities of daily living, it is highly important that the device be
compact, light in weight and portable. It is even more important
that the device be comfortable and safe to use. As different
people have different hand sizes, the assistive hands must be
designed considering the variety of hand sizes that can be
accommodated without any compromise in safety or comfort.
This can be best achieved by making use of a joint-less structure
that takes the shape of the hand that wears it. This paper
proposes the design of an assistive device that is lightweight,
compact, safe and comfortable. This device assists the hand in
gripping objects used in daily life activities. The performance
evaluation of this device is carried out by measuring the gripforce
exerted by the finger-tip on the object. The maximum
range of grip-force exerted by this assistive hand is between 2.5
to 4.5 N. The minimum grip-force that can be applied is 0.9 N.
The experiments conducted show the viability of the assistive
device. |
