Flexible actuators are devices that convert energy into motion, allowing them to bend or stretch in response to various stimuli. They are often made from soft materials, enabling them to adapt to different shapes and surfaces. These actuators are commonly used in robotics, prosthetics, and soft robotics, where traditional rigid actuators may not be suitable. The design of flexible actuators can vary widely, incorporating technologies such as pneumatics, electroactive polymers, or shape memory alloys. Their versatility makes them ideal for applications requiring gentle handling or complex movements, enhancing the functionality of devices in fields like medical technology and automotive engineering.
