Photopatterning of a photoreversible cova­lent elastomeric network under mechanical strain, or mechanophotopatterning, provides a facile approach to fabricate complex topographical features using elementary irradiation schemes. A photoresponsive material is deformed in two dimensions and irradiated through a mask, resulting in a transparent material with topography that reflects the concentric rings of the mask.
