Measured transmission spectra for the Au NHA on top of a responsive pNIPAAm hydrogel cushion (Au NHA-hydrogel) (a) in contact with air and water at T = 22 °C. (b) The swollen hydrogel cushion in contact with water spiked with ethylene glycol (EG, n0 = 1.33–1.37) at T = 22 °C. (c) Au NHA-hydrogel in water (n0 = 1.33) with temperature varied in the range of T = 22–45 °C in order to actuate the pNIPAAm cushion. (d) The collapsed cushion in contact with water spiked with ethylene glycol (n0 = 1.33–1.37) at T = 40 °C.
