What are microdots and how are they created?
Microdots are microscopic discs made of a variety of materials, such as metal, plastic, or ceramic, that contain tiny amounts of information. They are created through a process called microfabrication, which involves etching, cutting, or printing tiny patterns onto a surface. The information stored on microdots can be in the form of text, images, or even small amounts of data.
The creation of microdots requires specialized equipment and techniques, such as 3D printing, laser etching, or photolithography. The process involves designing the pattern or information to be stored on the microdot, followed by the actual fabrication of the dot. The resulting microdot is then inspected for quality and accuracy before being used in various applications.
What are some common practical applications of microdots?
Microdots have a wide range of practical applications across various industries. One common use is in product authentication, where microdots are embedded with unique identifiers or serial numbers to verify the authenticity of a product.
