Synthesis and operating principle of mechanical cloaking with DAE-crosslinked microgels including stylized phase diagram. Non-irradiated, swollen microgels are susceptible to shear force in solution and degrade rapidly by fragmentation. Conversely, UV-irradiation of the microgels within the VPTT shift window leads to a transition from the swollen to the collapsed state, thus enabling mechanical cloaking and increasing the resistance against shear force in solution.
