Layered Structures

Definition

Layered structures refer to the design and arrangement of materials in distinct layers, where each layer can have different properties and functions. This concept is particularly significant in soft robotics, as it allows for the integration of various mechanical, thermal, and electrical properties within a single system. By utilizing layered structures, engineers can create components that are lightweight yet strong, flexible yet resilient, enhancing the performance and capabilities of robotic systems.
