multakerros

Multakerros is a Finnish term used to describe anything made up of multiple layers. The word combines 'multi-' meaning many and 'kerros' meaning layer. It is commonly used in Finnish-language technical writing to characterize structures, coatings, or systems that consist of more than one distinct layer, often with different materials, properties, or functions.

In geology and earth sciences, multakerros can describe stratified rock formations or sedimentary sequences where several bedding planes or mineral layers are stacked. In materials science and engineering, the term is frequently used for multilayer coatings and laminates, such as protective coatings, dielectric mirrors, or optical coatings, where alternating layers of different materials tailor mechanical, optical, or barrier properties.

In electronics and design, multakerros is applied to laminated or stacked structures, including multi-layer printed circuit boards, laminated glass, or composite panels, where layer-by-layer construction provides strength, insulation, or optical performance. In computing and information technology, the concept appears in reference to layered architectures or systems composed of several functional layers, from transport and data layers to presentation tiers, and in neural networks where multiple processing layers are used.
