Artificial muscles are materials or devices that can mimic the movement and function of natural muscles. They can expand, contract, and change shape in response to stimuli, such as heat or electricity. These innovative technologies are being developed for various applications, including robotics, prosthetics, and even soft robotics, where flexibility and adaptability are essential. Researchers are exploring different materials, like polymers and shape-memory alloys, to create these artificial muscles. By imitating the way biological muscles work, scientists aim to enhance the performance of machines and improve the quality of life for individuals who rely on prosthetic limbs or other assistive devices.
