Incorporation of the mechanophore into the polyurethane polymer.
Top: The mechanophore molecule is inserted within the short, tightly packed units of the polyurethane polymer. Bottom: when a physical force (in this case stretching indicated by the symbol F) is applied onto the polymer while under an excitation source (here a UV light), the mechanophore will increase the intensity of the emitted light (here shown as Force).
