New improved artificial muscles developed

The POSTECH research group has developed a new concept of polymer electrolyte with various

functional groups, this should fix the problem of existing artificial muscles for robots. Discuss

Recently, research has been carried out onequipping robots with artificial muscles. However, the powerful strength and high speed of artificial muscles cannot be realized at the same time, because the mechanical strength and conductivity of the polymer electrolyte - the key materials that drive the actuator - have conflicting characteristics.

This polymer electrolyte is capable of both ionic,and to hydrogen bonds, which opens up the possibility of resolving these contradictions. The results of the study were recently published in the international scientific journal Advanced Materials.

Artificial muscles are used torobots moved their limbs as naturally as humans. To control these artificial muscles, an actuator is needed that demonstrates mechanical transformation under low voltage conditions.
