我们展示了微环组装聚丙烯酰胺（PAM）微纤维高灵敏度相对湿度（RH）传感。当暴露于湿气时，PAM超细纤维吸收水分子并随着湿度的增加而单调膨胀，导致胶束的共振峰的明显光谱移动。通过测量光谱位移，在5%至71%RH的动态范围内，该微片显示出高达490 pm/%RH的灵敏度和约120 ms的响应时间。(C)2011年美国光学学会
We demonstrate microrings assembled with polyacrylamide (PAM) microfibers for high-sensitivity relative humidity (RH) sensing. When exposed to moisture, the PAM microfiber absorbs water molecules and inflates monotonically with the increasing humidity, resulting in evident spectral shifts of the resonance peaks of the microring. By measuring the spectral shifts, the microring shows sensitivity as high as 490 pm/%RH and a response time of about 120 ms, within a dynamic range from 5% to 71% RH.
