What is the most common shape memory polymer?
Triple-shape memory While most traditional shape-memory polymers can only hold a permanent and temporary shape, recent technological advances have allowed the introduction of triple-shape-memory materials.
What is polymer actuator?
An electroactive polymer (EAP) is a polymer that exhibits a change in size or shape when stimulated by an electric field. The most common applications of this type of material are in actuators and sensors. The majority of historic actuators are made of ceramic piezoelectric materials.
What is shape memory materials?
Shape memory materials (SMMs) are featured by the ability to recover their original shape from a significant and seemingly plastic deformation when a particular stimulus is applied1. This is known as the shape memory effect (SME).
What are shape memory polymers made of?
The shape-memory polymer network consists of covalent netpoints and switching segments based on a physical interaction. To display shape-memory functionality, the polymer network has to be temporarily fixed in a deformed state under environmental conditions relevant to the particular application.
What are electroactive polymers used for?
Due to their interesting properties, polymers are used in various applications, such as construction materials, automotive parts, plastics, and clothing. Electroactive polymers (EAPs) are a type of flexible, elastic polymer (elastomer) that change size or shape when stimulated by an electric field1,2.
How are shape memory alloys work?
– Biggest thing would be mechanical Artificial Heart valves. – Artificial Lower Jaw opens & closes but remains closed by default. – Artificial prosthetics to replace cartiligious body parts like ear, nose tip etc. – Basically any body muscle that requires tension & compression frequently but remains either tensed or compressed by default.
What are shape memory materials?
The transition of these alloys from their high-temperature stronger form to low-temperature weaker form results in a phase change in their crystal structure. The inherent phase shift allows shape memory alloys to display compelling properties like super elasticity and shape memory effect.
