Abstract

pH-Sensitive hydrogels are networks of polymers that can imbibe a solution and swell. They are used in many smart engineering devices. One of such applications is a diffractometric biochemical sensor. This sensor is composed of a hydrogel grating fixed on a hard substrate that can swell due to pH changes. The aim of the present study is to develop a numerical model of such a bi-material device used to measure pH value of a solution.
