Soft magnetic exoskin transducing human motion

Project description

Magnetic sensors improve functionality in wearable robots

Wearable robotics, once dominated by rigid exoskeletons, is transitioning to soft exosuits, which still provide remarkable human motor assistance. However, these exosuits often lack intuitive control systems, which adds cognitive load to users. Traditional motion detection technologies, like inertial measurement units, are unreliable due to issues such as sensor drift and limited battery life. This creates a significant barrier to developing wearable robots that seamlessly integrate with human movement. With the support of the Marie Skłodowska-Curie Actions programme, the SCOUT project will develop a new sensor system using passive magnetic markers. This ‘magnetic exoskin’ will be used to accurately decode human motion in real-time, paving the way for more intuitive and effective wearable robots with applications in various fields.

Objective

Wearable robotics is undergoing a disruptive transition, from rigid exoskeletons to lightweight soft robotic
exosuits, which have achieved remarkable results in human motor assistance and augmentation. These devices,
however, still lack intuitive control approaches imposing additional cognitive load on their users. A future
wearable robot that can help us to walk, run, jump, dance, and restore independence in people with neuromuscular
impairments, requires the key ingredient to achieve the symbiotic connection between the user and the robot. In the
classical control strategy for wearable robots, inertial measurement units (IMUs) are often exploited to detect
user’s motion intention. Although the latter are valuable wearable tools, their reliability and accuracy are often
debated, due to their drift and poor battery life (being powered), raising challenges for researchers and engineers to
improve their stability over time. The SCOUT project aims to break this technological bottleneck by developing a
novel wearable artificial sensor system based on passive magnetic markers to detect human motion.
Inspired by the natural human sensorimotor system, and exploiting recent advances in magnets localization, a soft
magnetic exoskin will be designed to transduce joints motion of the user into decipherable magnetic fields. These
will be decoded by a central interpreting unit to have a real-time, reliable, and robust measure of human kinematics
without the need of time-consuming parameter tuning and calibrations. Besides the intended benefit for current
wearable robots, this project could develop a novel human-machine interface with wide potential for a diverse
range of applications, such as human motion analysis, ergonomics, virtual reality, and robotic teleoperation.
