Abstract Self-assembled hyaluronic acid (HA) microspheres are utilized for memorable optical humidity sensing. Because of the extremely high hygroscopic property of HA, the microsphere deforms in a highly humid atmosphere and the shape change is irreversible, thereby memorizing the history of the humidity change. The optically memorable humidity sensor can notify whether the humidity exceeds the upper limit of 50%.
