Artificial muscles, also known as muscle-like actuators, are devices or materials that can mimic natural muscles. They can change stiffness, contract, expand, or rotate with an external stimulus, such as electricity. Artificial muscles can be made from a range of materials, including metal coils or sheets of plastic, and can be constructed quickly and cheaply. They are highly flexible and have wide applications in medicine, robotics, industry, and many other fields.

What You'll Learn
Artificial muscle-like actuators
Each artificial muscle consists of an inner "skeleton" made from materials such as metal coils or sheets of plastic folded into specific patterns. This is surrounded by air or fluid and sealed inside a plastic or textile "skin". Artificial muscles are highly flexible and lightweight, and they can generate about six times more force per unit area than mammalian skeletal muscle.
MIT researchers have developed a new method to grow artificial muscles for soft robots that can move in multiple directions. They used a technique called "stamping" to create an artificial iris-like structure by 3D-printing a tiny stamp with microscopic grooves. This stamp is then pressed into a soft hydrogel to create a blueprint for muscle growth.
Artificial muscles have a wide range of applications in medicine, robotics, and industry. They can be used to build biohybrid robots powered by soft, artificially grown muscle fibres, and they can also replace electric motor actuators to reduce weight and noise while allowing for precise control.

Artificial muscle tissue
Each artificial muscle consists of an inner "skeleton" made of various materials, such as a metal coil or a sheet of plastic folded into a certain pattern. This is surrounded by air or fluid and sealed inside a plastic or textile bag that serves as the "skin".
Artificial muscles are highly flexible and have wide applications in medicine, robotics, industry and many other fields. They can be powered by a vacuum, which makes them safer than most other artificial muscles currently being tested. They can also be powered by electricity, which facilitates mechanical motion.

The use of electricity to facilitate mechanical motion
Robotic muscles, also known as muscle-like actuators, are devices or materials that can mimic natural muscles and change stiffness, contract, expand or rotate with an external stimulus. The aim is to mimic human muscles as closely as possible, including producing similar motions.
Electricity is used to facilitate mechanical motion in robotic muscles. These muscles are highly flexible and have wide applications in medicine, robotics, industry and many other fields. They are also incredibly lightweight and resilient. A 2.6-gram muscle can lift a 3-kilogram object, which is the equivalent of a mallard duck lifting a car.

In addition, the inner skeleton can be designed and patterned to facilitate specific movements or functions. For instance, the "stamping" technique developed by MIT researchers involves 3D-printing a tiny stamp with microscopic grooves, which is then pressed into a soft hydrogel to create a blueprint for muscle growth. This technique allows for the creation of artificial muscles that can flex and twitch in multiple, coordinated directions, mimicking the complex movements of the iris of an eye.
