聚(N-异丙基丙烯酰胺)-丙烯酸微凝胶已被证明具有可见的颜色和独特的光谱。虽然已经在整个标准具上研究了这些特性，但尚不清楚标准具的光学特性是否可以在同一标准具的空间隔离区域上独立调制。在这里，我们表明，空间隔离区域的光学特性确实可以根据温度和 pH 值而独立改变。这是通过可见颜色变化和反射光谱显示的。此外，可以在柔性设备上制造标准具，并单独调制独立点的颜色。
Poly(N-isopropylacrylamide)-co-acrylic acid microgels have been shown to exhibit visible color and unique optical spectra. While these properties have been studied on whole etalons, it is unclear if the etalon's optical properties can be independently modulated on spatially isolated regions of the same etalon. Here we show that indeed the optical properties of spatially isolated regions can be changed independently in response to temperature and pH. This was shown via both visible color changes and reflectance spectroscopy. Furthermore, etalons on flexible devices could be fabricated, and the color of independent spots separately modulated.
