This eBook provides a comprehensive treatise on modern biomechatronic systems centred around human applications. A particular emphsis is given to exoskeleton designs for assistance and training with advanced interfaces in human-machine interaction. Some of these designs are validated with experimental results which the reader will find very informative as building-blocks for designing such systems. This eBook will be ideally suited to those researching in biomechatronic area with bio-feedback applications or those who are involved in high-end research on man-machine interfaces. This may also serve as a textbook for biomechatronic design at post-graduate level.
