Exoske is the commonly used short abbreviation for exoskeleton, referring to wearable bionic mechanical devices worn on the human body to boost physical performance or support rehabilitation therapy. These devices are mainly divided into passive and powered versions for industrial labor protection, medical rehabilitation, emergency rescue and other scenarios. Made from lightweight and high-strength carbon fiber and aviation aluminum alloy, exoske features adjustable joints and flexible binding structures to fit users of different body shapes without restricting normal limb movements. Passive exoske relies on elastic components and mechanical leverage to disperse waist, shoulder and knee loads during frequent lifting, bending and long-time standing work, effectively easing muscle fatigue and cutting the risk of occupational strain injuries. Powered exoske is equipped with precision sensors, servo drive systems and intelligent control modules, which can capture human motion intentions in real time to assist patients with paraplegia, hemiplegia and lower limb weakness in completing standardized gait training, preventing complications including muscle atrophy and joint contracture. Built-in safety functions such as anti-fall protection and emergency stop guarantee stable and secure operation. With mature technical development, exoske has gradually become essential smart equipment to protect workers’ physical health and help mobility-impaired groups restore self-care ability and life confidence.
