A Review on Current Mechanical and Electronic Design Aspects and Future Prospects of Smart Canes for Individuals with Lower Limb Difficulties

Abstract

Smart canes are one of the mobility assistive devices to facilitate the freedom of movement and help people with mobility problems to move around and perform daily chores, which are not possible usually. But they are available in different design options to offer specific advantages. In this review paper, we have addressed different mechanical and electronic designs of assistive devices proposed and developed by various researchers. The aim of our study was to sort out different mechanisms of actions used by them. With the discussion and comparison of their mode of functions, we have found a direction to potential future improvements, development, and variations to fulfill individualized and customized requirements.
