In the previous study, Local stability of the spine and hip was affected by fatigue
during repetitive lifting. Progressive fatigue could increase the risk of injury to the
spine and hip. [9]
There are many kinds of research to evaluate human fatigue by
measuring vital information, but research such as measuring fatigue from behavior
algorithm of workers who work repetitively like handling heavy goods has not been
done. The motion analysis suggests the relationship between gradual accumulation of
fatigue and an increase of duration during the lifting test. In the latter half of the test, it
was confirmed that there were three or more occurrences of values exceeding the
average so far and that the values included one or more occurrences of 1.23 or more.
This result suggests that IoH/ IoT sensor could detect the algorithm in the duration
between the motion of joint flexion and extension and alert their manager or worker
them self when the worker is about to reach their limit of fatigue. The validity of this
trend shall be examined with more subject and algorithm should be considered. A new
generation of Assist Suit could be installed with the functions to prevents accidents due
to fatigue in advance.
The result of the comparison test of the strength of coil springs suggests that the
strength of the coil spring effects reduction of workload. However, the difference of
subject weight may have significance on the evaluation of the assistance felt, so it must
be verified with more subject. In this test, as the workload got higher, higher spring
strength enabled better reduction of workload.
