The self-sealing suction cup is a suction cup that exerts a suction force only when it is in physical contact with an object. Unlike most other suction cups, it does not exert any suction force when it is not in contact with an object. [1] Its grasping ability is achieved entirely through passive means without the use of sensors, valves, or ...
The working face of the suction cup is made of elastic, flexible material and has a curved surface. [3] When the center of the suction cup is pressed against a flat, non-porous surface, the volume of the space between the suction cup and the flat surface is reduced, which causes the air or water between the cup and the surface to be expelled past the rim of the circular cup.
A suction cup is placed onto the head of the baby and the suction draws the skin from the scalp into the cup. Correct placement of the cup directly over the flexion point, about 3 cm anterior from the occipital (posterior) fontanelle, is critical to the success of a vacuum extraction.

Nano-suction is a technology that uses vacuum, negative fluid pressure and millions of nano-sized suction cups to securely adhere any object to a flat non-porous surface. When the nano-suction object is pressed against a flat surface, millions of miniature suction cups create a large vacuum, generating a strong suction force that can hold a ...
