Abstract
Optical sensors whose performance depend on materials having quite different mechanical properties are investigated. These properties include negative Poisson's ratio and negative linear compressibility. Because of the symmetry of the elastic constant compliance matrix, a material that has a negative linear compressibility should increase the density when stretched in an appropriate direction. Such a material is referred to as stretched-densified, which is a distinctly different property than having Poisson's ratio. Both the stretch-densification property and negative Poisson's ratios can be used to obtain enhancements in the sensitivity of optical sensors for the measurement of stress, strain, or environmental influences that produce either of two.
