👉 Ghost engineering refers to the practice of manipulating the physical and chemical properties of materials at a microscopic level without altering their macroscopic appearance or function, often to enhance performance or introduce novel characteristics. This technique leverages advanced nanotechnology and materials science to engineer surfaces, structures, or compositions that exhibit unique properties, such as increased strength, improved conductivity, or enhanced biocompatibility. By doing so, ghost engineering allows for the creation of materials that can surpass the limitations of traditional manufacturing methods, enabling innovations in fields like electronics, aerospace, and biomedical engineering. The term "ghost" in ghost engineering implies that these modifications are subtle and not immediately apparent, yet they can have profound impacts on the material's behavior and utility.
