Abstract
In a solidification sensor for measuring a solidification state of a liquid with a high degree of accuracy in real time, and for making the sensor small-sized with a reduced power consumption, the solidification sensor comprises a liquid absorbing portion formed of a liquid absorbable material, a substrate coupled to the liquid absorbing portion and a strain sensor for measuring strain exerted to the substrate due to a volumetric change upon solidification of a liquid absorbed in the liquid absorbing portion.
