# Materials; Polymers; Measuring Stiffness of Soft Polymers

NIST researchers developed a new high-speed method for measuring the stiffness of soft-polymer materials like those used in contact lenses. The test material is covered with a sensor film, and the combination is compressed until it buckles. The resulting pattern of ridges is the key to determining stiffness, an important material property.
