Abstract: A human body detection mat is provided to analyze a user's sleep and selectively generate heat in a partial area thereof. The human body detection mat can include a substrate, a plurality of first detection electrode lines arranged on the substrate and formed along a first direction, and a plurality of second detection electrode lines arranged on the substrate and formed along a second direction which intersects with the first direction. The first and second detection electrode lines intersect with each other within a specific area on the substrate and are formed to be flexed within the specific area.

Abstract: A human body sensing mat can sense the movement of a human body and analyze a user's sleep. The human body sensing mat may include a substrate; a plurality of fiber sensors for generating signals according to a distance to a specific object; a sensor array disposed on the substrate; a shield layer for covering the sensor array; and a driving unit for applying a voltage to the sensor array. Each of the fiber sensors is disposed on a central portion of the substrate and on both ends of the substrate. The fiber sensors that are respectively disposed in the central portion and end portions of the mat can sense the user's breathing, tossing and turning, and the like regardless of the user's posture. Accordingly, the user's sleep can be analyzed regardless of the user's posture.
