Surgery is one of the primary treatment modalities for gastrointestinal tumors but can lead to postoperative ileus (POI), which can aggravate pain and increase costs. The incidence of POI can be effectively reduced by monitoring bowel sounds to assist doctors in deciding the timing of transoral feeding. In this study, we prepared a flexible strain sensor based on a graphene composite material and tested the feasibility of sensor monitoring of bowel sounds using simultaneous stethoscope and sensor monitoring. We found that the time of hearing the bowel sounds (12.0-12.1 s) corresponded to the time of waveform change monitored by the sensor (12.036 s), and the sound tone magnitude corresponded to the waveform amplitude. This proves that the application of sensors to monitor bowel sounds is feasible, which opens up a new field for the application of graphene sensors and provides a new way for clinicians to judge the condition of the intestine.
手术是胃肠道肿瘤的主要治疗方式之一，但可能导致术后肠梗阻（POI），这会加重疼痛并增加费用。通过监测肠鸣音可以有效降低POI的发生率，以帮助医生确定经口进食的时机。在本研究中，我们制备了一种基于石墨烯复合材料的柔性应变传感器，并通过同时使用听诊器和传感器监测来测试传感器监测肠鸣音的可行性。我们发现听到肠鸣音的时间（12.0 - 12.1秒）与传感器监测到的波形变化时间（12.036秒）相对应，且音调大小与波形幅度相对应。这证明了应用传感器监测肠鸣音是可行的，为石墨烯传感器的应用开辟了新领域，并为临床医生判断肠道状况提供了新途径。
