Traditional posture correction products have a good back, and the human body is passively corrected by a large external force, which is easy to cause discomfort and resistance. The posture reminder, a new generation of posture correction products, overcomes the shortcoming that traditional products only rely on external force to correct and make people feel uncomfortable. Japan's high-sensitivity bending sensor is used to detect the posture of human back. When the human body appears hunchback, the posture reminder will vibrate slightly to remind people to keep their posture straight in time to prevent hunchback and myopia. Compared with the traditional health care posture correction products, with the active participation of some people, it can correct human posture more effectively, and it is comfortable and easy to accept when used.
