Biofeedback is known to improve postural control and shorten rehabilitation periods among the young and elderly. A biofeedback system communicates with the human central nervous system through a variety of feedback modalities. Vibrotactile feedback devices are gaining attention due to their desirable characteristics and simplistic manner of presenting biofeedback. In this study, we investigate the potential of incorporating a real-time biofeedback system with artificial intelligence for wobble board training, aimed at improving ankle proprioception. The designed system utilizes vibrotactile actuators to provide forewarning for poor postural control. The biofeedback system depended on Euler angular measurements of trunk and wobble board displacements, from inertial measurement units (IMUs). A fuzzy inference system was used to determine the quality of postural control, based on IMU-acquired measurements of trunk and wobble board. The designed system integrates: 1) two IMUs, 2) a fuzzy knowledge base, and 3) a feedback-generation module. Tests were conducted in eyes-open and eyes-close conditions while standing on the wobble board to assess viability of the system in providing accurate real-time intervention. The results observed an improvement in postural control with biofeedback intervention, demonstrating successfulness of the prototype built for improving postural control in rehabilitative and preventive applications.

This article addresses the general theme of wearable technology from an oblique angle — via performance studies — by examining the performative basis of interactions between humans and machines. The author considers the developing nature of human robot relations in Japan, and raises concerns relevant to discussions of wearable technologies.

Review

«Back in the sixties, when I first dreamed up the concept of Iron Man, I thought, ‘What if a man had a suit of armor, like the knights of old — but modern armor that housed all sorts of miniaturized, technical weaponry? Such a man would seem to be the ultimate superhero.’ At first, I didn’t give much thought to what that suit of armor might mean to the man inside — how it might affect his body and/or his brain and subtly blur the line between human and machine. But now, almost 40 years later, E. Paul Zehr has tackled that very subject. Inventing Iron Man is his fascinating vision of the real life implications of my original concept.» (Stan Lee, comic icon and creator of Iron Man) «E. Paul Zehr, surely one of the coolest of professors, has done something interesting, enlightening, and maybe just a bit quixotic; he has built a bridge between the fantasy science of superhero comics and the eyes-front innovations of real-life technological innovators.» (Dennis O’Neil, Iron Man writer and editor)»

Product Description

Tony Stark has been battling bad guys and protecting innocent civilians since he first donned his mechanized armor in the 1963 debut of Iron Man in Marvel Comics. Over the years, Stark’s suit has allowed him to smash through walls, fly through the air like a human jet, control a bewildering array of weaponry by thought alone, and perform an uncountable number of other fantastic feats. The man who showed us all what it would take to become Batman probes whether science-and humankind-is up to the task of inventing a real-life Iron Man. E. Paul Zehr physically deconstructs Iron Man to find out how we could use modern-day technology to create a suit of armor similar to the one Stark made. Applying scientific principles and an incredibly creative mind to the question, Zehr looks at how Iron Man’s suit allows Stark to become a superhero. He discusses the mind-boggling and body-straining feats Iron Man performed to defeat villains like Crimson Dynamo, Iron Monger, and Whiplash and how such acts would play out in the real world. Zehr finds that science is nearing the point where a suit like Iron Man’s could be made. But superherodom is not just about technology. Zehr also discusses our own physical limitations and asks whether an extremely well-conditioned person could use Iron Man’s armor and do what he does. A scientifically sound look at brain-machine interfaces and the outer limits where neuroscience and neural plasticity meet, Inventing Iron Man is a fun comparison between comic book science fiction and modern science. If you’ve ever wondered whether you have what it takes to be the ultimate human-machine hero, then this book is for you.

Several lower extremity exoskeletal systems have been developed for augmentation purpose. Common actuators, have important drawbacks such as complexity, and poor torque capacities. The main scope of this research is to propose a series elastic actuator for lower extremity exoskeletal system which was designed based on muscle functional analysis. For this purpose, a biomechanical framework consisting of a musculoskeletal model with ten degrees-of-freedom actuated by eighteen Hill-type musculotendon actuators per leg is utilized to perform the muscle functional analysis for common daily human activities. The simulation study illustrated functional differences between flexor and extensor muscles and the results were utilized for efficient design of the series elastic torque actuator employed in lower extremity exoskeletons.
