The invention relates to a diaper structure with wireless detection of wet state and a diaper detection system thereof.Including a diaper body,At least one communication chip,At least one metal antenna and one signal reader,The communication chip and the metal antenna are attached to the outside of the diaper body.And connected to each other,To form a radio frequency tag,When the diaper body is in a wet state,The change of the dielectric coefficient of the diaper body will change the impedance value of the metal antenna.In turn, the wavelength of the electromagnetic wave signal transmitted by the radio frequency tag is changed.Again,The signal reader can send a detection electromagnetic wave to the radio frequency tag.After receiving the detected electromagnetic wave, the radio frequency tag will transmit a response electromagnetic wave.So that the signal reader canDetermine whether the diaper body is wet.So,By the diaper detection system of the invention,The carer can change the user's diaper quickly.To avoid the need for caregivers to remove diapers from users one by one,Check the wet state of urine.Then one by one for the user to put back the heavy work of diapers.本發明係一種具無線偵測溼透狀態的尿布結構及其尿布偵測系統，包括一尿布本體、至少一通訊晶片、至少一金屬天線及一訊號讀取器，其中該通訊晶片與金屬天線係貼附在該尿布本體的外側，且彼此相互連接，以形成一無線射頻標籤(Tag)，當該尿布本體為溼透狀態時，因該尿布本體本身介電係數之改變會使該金屬天線之阻抗值隨之改變，進而令該無線射頻標籤所傳送之電磁波訊號的波長改變，又，該訊號讀取器能對該無線射頻標籤發射一偵測電磁波，該無線射頻標籤接收到該偵測電磁波後會傳送一回應電磁波，以使該訊號讀取器根據該回應電磁波的波長，判斷出該尿布本體是否溼透，如此，藉由本發明之尿布偵測系統，照護人員即可迅速地對使用者更換新尿布，以免除照護者必需逐一自使用者身上拆開尿布，檢視尿溼狀態，再逐一為使用者穿回尿布之繁重工作。
