Samsung, together with experts from Ajou University, announced the creation of CASA, the universal artificial muscles to be used with augmented reality headsets. Technically, they are metal springs in the form of wire springs, and the actuator can lift up to 800 times its own weight.

Thus, “muscles” weighing 0.2 grams can lift more than 170 grams. If the structure scales, CASA will be able to lift hundreds of kilograms, which would also be needed in robotics and exoskeletons.

As for the implementation of such “muscles” in AR/VR technologies, they can be used in virtual suits and gloves to tactilely feel digital objects. For example, you can pet a virtual cat.

In addition, the technology can be used in VR helmets to focus on one or another object, as in reality. It is not yet known when such technologies will appear in commercial solutions on the market. Source
