Metamaterials refer to any modification of the physical behavior of an existing material through the structured arrangement of repetitive patterns, procedurally generated, which can directly influence its response to deformation, thermal dissipation, and vibrational control. This creates possibilities for solutions that were previously difficult to achieve using conventional materials such as metals, ceramics, polymers, and their composites. The use of this technology has gained momentum with the advent of 3D printing, which has made it possible to apply and create these structures for practical validation. The first structures were modeled at the beginning of the last century, such as the creation of patterns to generate anomalous properties, with diverse applications in fields like optics, thermodynamics, and mechanics, as it allows for material design tailored to specific applications. As a result, applications have expanded to various scales, from millimeter-engineered materials to the nanoscale, drawing the attention of researchers from different fields, including healthcare. This interest stems from the vast array of possibilities and innovations driven by advancements in materials and additive manufacturing, combining these fields to generate increasingly adaptive solutions. In this paper, the concept of metamaterials will be introduced, followed by an exploration of various applications of this technology, including medical equipment, devices, prosthetics, orthotics, and implants, as well as potential future applications of this technology in healthcare.
