“…Aspirations to build lighter active orthosis, which would be useful in everyday life turned engineers' attention, in the aspect of applied materials, to alloys. Similar strength properties, significantly lower weight, and higher breaking tensile stress-to-density ratio (162) than steel were the reason why aluminium is often used in modern bionic orthoses [68,69]. In general, materials used to create an exoskeleton are: bakelite, surgical stainless steel, aluminium alloys (copper, magnesium, or manganese), acrylonitrile butadiene styrene (ABS), polylactide (PLA), or shape memory alloys (SMA) [44,68,[70][71][72][73][74][75].…”

Using robotics in modern medicine is slowly becoming a common practice. However, there are still important life science fields which are currently devoid of such advanced technology. A noteworthy example of a life sciences field which would benefit from process automation and advanced robotic technology is rehabilitation of the upper limb with the use of an orthosis. Here, we present the state-of-the-art and prospects for development of mechanical design, actuator technology, control systems, sensor systems, and machine learning methods in rehabilitation engineering. Moreover, current technical solutions, as well as forecasts on improvement, for exoskeletons are presented and reviewed. The overview presented might be the cornerstone for future research on advanced rehabilitation engineering technology, such as an upper limb bionic orthosis.

“…Ferrous material was found to be heaviest so it did not help the patients with their comfort level so they moved on to the non-ferrous materials such as Aluminum. Orthotic calipers aid in treatment of physical disabilities, provide support to the weakened muscles and help the polio affected patients from risks and fractures [4] (figure 1). Orthotic calipers holds the legs tight with the help of the leather straps and provides all the benefits due to which the polio affected survivors doesn't feel as if they are having weakened musclesand require anybody's support [5].…”

Increasing population has led to numerous disabilities. One such disability which should be taken into account is related to human gait. Polio patients mainly suffer from this kind of disability due to which their muscles get weakened and they are unable to walk properly. The handicapped patients require an appliance with the help of which they can walk without any difficulties and the appliance acts as an aid for the correct positioning of their joints. Presently Aluminum Alloy based calipers are used but still the patients urge for better comfort. The requirement apart from more strength and stiffness, durability at lesser cost, environment friendly and light weight. Composite material is one such material which provides lower weight to volume ratio, high strength and stiffness at lesser cost. The purpose of the authors is to compare the mechanical properties of presently used aluminum calipers with polymeric thermoset based matrix (Carbon cloth with epoxy) based on CAD tools. The comparison reveals that thermoset based matrix will provide the maximum strength and firmness when compared to presently used Aluminum based calipers and model designed on CAD tools. Hence, the usage of the composite material will help the researchers design orthotic calipers which will have higher strength at a lower weight.
