A Future Realistic Model of Bionic Limbs with High Accuracy

Abstract

Bionic limb achievements in the last 10 years have primarily focused on breakthroughs to improve accuracy with new materials and concepts that are unlikely to be used when producing an entire upper bionic limb. For example, studies on bionic limbs with new materials, such as pneumatic bionic flexible arms, which cannot meet the needs of amputees in terms of using comfortably and accurately interpreting users' intentions. Though the future development of bionic limbs has many possibilities, this paper summarizes and analyzes the functions and drawbacks of three most important structures in bionic hands and compares them to the most widely used sensory feedback realization methods. The paper then designed a future model based on the perspectives discussed above in order to meet the requirements of high accuracy, flexibility, a comfortable feeling, and real-time sensory feedback. Finally, the paper contrasts the BCI technique with the newly developed model.
