An optical resonator shifts their resonant frequencies in response to the change in the refractive index of the resonator matrix and thereby serve as an optical precise sensor. Here, we report an optical resonator that is solely made from liquid and shows a spectral shift of their resonance peaks in response to the change in their morphology. Detectable morphological change is successfully induced by the air flow and humid in the atmosphere, proving its potential utility as a flow and humidity sensor.
