Summary
Developing ideal prosthetic implants requires addressing challenges in biomimicry, control, and biocompatibility. Understanding tissue reactions and inflammatory responses is crucial for functional and comfortable robotic prosthetics.
Area of Science:
- Biomedical Engineering
- Biomaterials Science
- Prosthetics Research
Background:
- Current robotic prosthetic implants face challenges in meeting user needs for control, comfort, and aesthetics.
- Existing literature on prosthetics and robotic implants is extensive, necessitating a focused review.
Purpose of the Study:
- To identify key challenges and opportunities in prosthetic implant design.
- To review advancements and issues in biomimetic artificial hands and prosthetic control using electromyography (EMG) signals.
- To examine tissue reactions to implant materials and the impact of inflammation on sensor signal transmission.
Main Methods:
- Literature review focusing on four key areas: biomimetic artificial hands, EMG-based prosthetic control, implant material biocompatibility, and inflammatory responses affecting sensor function.
- Analysis of biological interfaces between implants and surrounding tissues.
Main Results:
- Challenges persist in achieving ideal prosthetic functionality, including ease of control, comfort, and cosmetic appeal.
- Tissue reactions and inflammatory responses at the biological interface significantly impact the performance and longevity of implanted sensors.
- Understanding pathophysiological changes at biological interfaces is vital for improving prosthetic biocompatibility.
Conclusions:
- Interdisciplinary collaboration among biomedical engineers, tissue engineers, biomaterial scientists, and biomedical scientists is essential for holistic and synergistic prosthetic design.
- Future prosthetic designs must prioritize biocompatibility and address the complexities of biological interfaces to meet user 'ideals'.
