The utility model relates to a smart diaper, which comprises a waterproof layer and a water absorbing layer. The water absorbing layer is adhered to the waterproof layer through a thread buckle. The waterproof layer is provided with a multi-resonance detecting circuit, a power control circuit and a bluetooth module. And a single-chip module, the multi-resonant detecting circuit is connected to the power control circuit and the single-chip module； the single-chip module is connected to the bluetooth module； the power control circuit is connected to the single-chip module, and the multi-resonant detecting circuit, the single-chip module and The Bluetooth module supplies power； the Bluetooth module sends the received data information to the outside； an electrode is disposed in the water absorbing layer, and the electrode is connected to the multi-resonant detecting circuit. According to the result of the circuit detection, it can be known that the multi-resonance detecting circuit loses the oscillation state once every time the urine is pulled, so that the number of times of pulling the urine can be known by the single-chip microcomputer module recording that the multi-resonant detecting circuit loses several oscillation states. Remind parents to change diapers in time, and can check the current diaper usage.本新型為一種智能紙尿褲，包括一防水層和一吸水層，該吸水層通過一絲扣與該防水層貼合，該防水層中鋪設有一多諧振盪檢測電路、一電源控制電路、一藍牙模塊與一單片機模塊，該多諧振盪檢測電路連接該電源控制電路和該單片機模塊；該單片機模塊連接該藍牙模塊；該電源控制電路連接該單片機模塊，給該多諧振盪檢測電路、該單片機模塊和該藍牙模塊供電；該藍牙模塊對外發送接收到的數據信息；該吸水層中鋪設有一電極，該電極連接該多諧振盪檢測電路。根據電路檢測的結果可以知道，每拉尿一次，該多諧振盪檢測電路就失去振盪狀態一次，所以通過該單片機模塊記錄該多諧振盪檢測電路失去幾次振盪狀態就可以知道拉尿的次數，提醒父母及時更換尿片，並且可以查詢當前尿片的使用情况。
