ELASTIC BODY MATERIAL HAVING PERIODIC STRUCTURE WHICH VARIES STRUCTURAL COLOR WITH MODULUS

摘要

PROBLEM TO BE SOLVED: To provide an elastic body material of a varying structural color; which may be usable in various fields such as functional members like a new strain sensor that is an inexpensive revolutionary type allowing easy visual recognition without using an expensive measuring device, a fuse element to impede propagation of light, or a short form gravimeter; devices; toys and so on.

SOLUTION: The elastic body material includes an elastic body sheet and a Bragg reflection region located on the surface of the elastic body sheet; provided that the Bragg reflection region includes monodisperse particles of a uniform particle size arranged spatially and periodically and an elastic body located in between and on the periphery of monodisperse particles, that the monodisperse particle consists of a polystyrene particle and that the elastic body consists of a polydimethylsilicone gel.
