Predictive Maintenance (PdM), also known as condition-based maintenance, attempts to evaluate the condition of equipment by performing periodic or continuous (online) equipment condition monitoring.
Just below the epidermis lies the second layer, the dermis. The dermis, although it contains blood vessels, nerves, and hair follicles, is primarily made up of a protein called collagen.. This protein forms a network of fibers that provides a framework for the growth of cells and blood vessels.ust below the epidermis lies the second layer, the dermis.

There are at least 16 types of collagen, but 80-90% of the collagen in the body consists of types I, II, and III. Type I collagen fibrils are stronger than steel (gram for gram). Collagen is most commonly found within the body in the skin, bones and connective tissues. The word collagen is derived from the Greek kolla, meaning glue. Collagen gives the skin its strength and structure, and also plays a role in the replacement of dead skin cells.
