Abstract: The invention relates to a hydration sensor comprising a sensing module operably disposed on a target area of interest of skin of a living subject for detecting data associated with thermal properties of the skin; and a wireless platform coupled with the sensing module for wireless data transmission between the sensing module and an external device. The sensing module comprises a thermal actuator for operably heating the target area of interest thereof; and a sensing circuit for simultaneously detecting a transient temperature change thereof to determine thermal properties of the skin.
