3. From the observation of a group with cerebral palsy we found that one of the
major limitations of the group is the control of their fine movements. So our
goal was to design a solution that minimized this muscular effort providing
greater independence in daily tasks, thus providing greater self-esteem. The
proposed solution may also include people with Parkinson's disease, muscle
problems, elderly and professionals that require precision in their tasks, such as
surgeons, for example.
In order to cover the various tasks that a person may need the fine movements,
we decided on a solution that was an artificial muscle. We decided by an outfit
that would help in these movements. We were inspired in the spider web to
check for a tough, flexible mesh and decided for graphene by properties such as
conductivity, flexibility, lightness, transparency and touch. And the carbon
nanotube involve graphene assisting in contraction and expansion of the
material.
