What Is a Powered Exoskeleton?
Powered exoskeletons are wearable devices designed to reduce physical strain during activities such as lifting heavy objects and walking. These suits may include motorized and hydraulic actuators, and some models operate on air pressure without needing an external power source.
These exoskeletons find applications across various sectors, including agriculture, manufacturing, and healthcare. With an aging workforce becoming more prevalent, especially in manufacturing, the demand for powered exoskeletons to alleviate physical strain is on the rise.
Structure and Effects of Powered Exoskeletons
Powered exoskeletons typically feature actuators such as motors or hydraulic systems and are worn over the limbs to aid movement. Some models are equipped with sensors that detect changes in muscle activity and stiffness, adjusting their support accordingly.
Non-electric powered exoskeletons are also available, offering ergonomic designs that minimize lower back strain and are compatible with regular work clothes and harnesses. These exoskeletons utilize the power of artificial muscles driven by air pressure and are designed for easy wearability.
Choosing the right size and wearing powered exoskeletons correctly is crucial to their effectiveness. Trials are recommended to ensure compatibility with the intended use, specific tasks, and the user’s physique.
Uses of Powered Exoskeletons
Powered exoskeletons are increasingly used in various industries, thanks to advancements in materials, sensor technologies, and motor miniaturization. They are particularly beneficial in sectors requiring frequent heavy lifting or prolonged periods of bending, such as agriculture, logistics, construction, and manufacturing.
They also support older adults in enhancing mobility and assist caregivers in tasks like transferring patients or assisting with personal care. For example, during the Tokyo Olympics and Paralympics, powered exoskeletons helped staff manage heavy lifting tasks, like changing weights for powerlifting events.
Powered Exoskeletons in Agriculture
In agriculture, powered exoskeletons assist in tasks requiring prolonged sitting or squatting, reducing lower back strain. They are adaptable for diverse users, including older adults and women, and can facilitate carrying heavy loads like harvest containers and tools.
Powered Exoskeletons in the Manufacturing Industry
Back pain, a major cause of workplace accidents in manufacturing, can be addressed by incorporating powered exoskeletons. With an aging skilled workforce and increasing participation of women and older workers, powered exoskeletons are becoming vital for reducing physical strain and enhancing workplace safety.
