Abstract: A human body sensing mat for sensing the movement of a human body, comprises: a substrate; a sensor array including a plurality of fiber sensors for generating signals according to a distance to a specific object, and disposed on the substrate; and a driving unit for applying a voltage to the sensor array, wherein the sensor array includes a plurality of sensing lines arranged in parallel in a first direction, and regarding the plurality of sensing lines, a first distance between neighboring sensing lines connected to different electrodes is greater than a second distance between neighboring sensing lines connected to the same electrode. The human body sensing mat can analyze user's movements and biometric signals regardless of the user's posture.

Abstract: Disclosed are a posture detection device and a posture detection method that can identify a user and determine the posture of a user by using artificial intelligence technology. An operation method of an electronic device to which artificial intelligence technology is applied includes acquiring sensing data measured by each of a plurality of sensors, determining whether a posture of a user is changed on the basis of the sensing data, acquiring statistical sensing data by statistically processing the sensing data when it is determined that the posture is changed, and identifying the user and determining the posture of the user on the basis of the statistical sensing data. With the use of an artificial intelligence machine learning technology, it is possible to improve posture determination accuracy and user identification accuracy.
