Researchers in South Korea have created a robot that can be worn like clothing, equipped with tissue muscles capable of generating lifting force up to 15 kg, combining advanced technology with a lightweight design that allows the user to receive mechanical support without the need for bulky and heavy devices.
This innovation relies on microfibers with a diameter of about 25 micrometers, which is about a quarter of the diameter of a human hair, woven to form threads that act as artificial muscles that contract when heated and return to their normal length when cooled, allowing for significant mechanical force production relative to the weight of the lightweight device.
The device resembles a vest or coat, equipped with sensors to monitor joint movements such as the shoulder and elbow, where the system controls the amount of energy sent to the tissue muscles to provide support only when needed, maintaining the flexibility of movement and user comfort.
The robot weighs less than 2 kg, making it feel similar to regular clothing, with the ability to assist the user in lifting objects or performing heavy movements effectively.
