An induction pad includes a first induction layer (10), a second induction layer (20) and a spacer layer (30). The second induction layer (20) has at least one second sparse induction zone (21) and at least one second dense induction zone (22). The spacer layer (30) is disposed between the first induction layer (10) and second induction layer (20), and includes at least one high pressure spacer zone (31) and at least one low pressure spacer zone (32). The second induction layer (20) is pressed downwards upon receiving a load to compress the spacer layer (30) and contact the first induction layer (10) to generate electric connection, thereby detecting the pressed location. Through the dense induction zone (22) and sparse induction zone (21) distributed on the second induction layer (20) whether a person is lay on a bed can be judged to reduce faulty judgments, and the posture of the person can be detected to better understand conditions of the person lay on the bed. |
