Wearable Robotics: Systems and Applications provides a comprehensive overview of the entire field of wearable robotics, including active orthotics (exoskeleton) and active prosthetics for the upper and lower limb and full body. In its two major sections, wearable robotics systems are described from both engineering perspectives and their application in medicine and industry. Systems and applications at various levels of the development cycle are presented, including those that are still under active research and development, systems that are under preliminary or full clinical trials, and those in commercialized products.
This book is a great resource for anyone working in this field, including researchers, industry professionals and those who want to use it as a teaching mechanism.
Key Features
- Provides a comprehensive overview of the entire field, with both engineering and medical perspectives
- Helps readers quickly and efficiently design and develop wearable robotics for healthcare applications
