Abstract

Mechanochromism of polymer-dye blends can be used to formulate novel pressure sensors for fluid mechanics and hydrology, where the use of traditional electromechanical transducers may be limited by environmental factors. Here, we investigate optomechanical properties of a mechanochromic blend of thermoplastic polyurethane and 0.5 wt% bis(benzoxazolyl)stilbene fluorescent dye. We characterize the response of this soft active material in a stress relaxation test by simultaneous acquisition of the tensile load, the mechanical deformation, and the fluorescence emission.
