This collapse allows the solid rubber center to move downwards, forcing the top membrane layer against the bottom layer, and completing the circuit.

The retina consists of membrane layers in the eye that receive visual images.

The material contains a membrane layer which is set to a predetermined temperature range.

"Then it has to be the membrane layer from the inner side of the hide of a very big animal, somehow removed in one piece."

The thicker porous membranes sometimes provide support for the thin dense membrane layers, forming the asymmetric membrane structures.

A disadvantage is the high sensible heat loss, as the insulating properties of the single membrane layer are low.

The cell is surrounded by a pellicle of three membrane layers (the alveolar structure) penetrated by micropores.

A bottom 0.2 m track etched polycarbonate membrane layer provides flow-rate control by creating a pressure drop and therefore a constant sweat flow.

Much research is carried out into thin amorphous films as a gas separating membrane layer.

Many plastids, particularly those responsible for photosynthesis, possess numerous internal membrane layers.
