Scientists Develop Artificial Muscles with 34 Times Higher Force than Weight
Scientists from the KAIST Korean Research Center have developed a unique device of artificial muscles capable of force 34 times higher than its own weight. Such an innovation will find application in soft robots, medical devices, and wearable devices that have already become part of our daily life.
The team, led by Professor Ilkvon about from the Faculty of Mechanical Faculty Kaist, developed a soft fluid switch operating during a supername voltage.
The artificial muscles that simulate human provide flexibility and naturalness of movements, which makes them a key element in soft robots and medical devices. They respond to external stimuli, such as electricity, air pressure, and temperature change. Control over these movements is an important task.
Traditional motors are inconvenient for use in limited space due to their rigidity and large size. To solve this problem, the team developed an electro-ion soft actuator to control fluid flow, producing significant forces even in a narrow space.
The artificial muscle, created from metal electrodes and ion polymers, generates strength and movement in response to electricity. To create an impressive force relative to its weight with a power of power (~ 0.01 V), a polysulfoned covalent organic frame (PS-COF) was used.
The artificial muscle, with a thickness of only 180 microns, was valid 34 times higher than its weight (10 mg), while providing smooth movement. This allowed the team to accurately control the direction of fluid flow with low energy consumption.
Professor Ilkvon O, the head of the study, noted: “Electrochemical soft fluid switch operating with a power of power opens up many opportunities in the areas of soft robots, soft electronics, and microfluids based on
