Conventional methods of intestinal inspection play an essential role in the assessment of bowel diseases and other relevant health issues, yet fail to obtain intestinal conditions in real time because of radiation limits and operation inconvenience. Herein, a flexible, skin-mounted device is developed for longterm, real-time monitoring, and for the evaluation of bowel sounds based on the integration of a threedimensional printed elastomeric resonator with flexible electronics. The device is

Clinical tests conduct in a normal volunteer and in patients with mechanical intestinal obstruction or paralytic ileus illustrate the usefulness of the device in capturing the characteristics of bowel sounds. Furthermore, a demonstration of collection and classification of bowel sounds by the flexible device based on machine learning methods can serve as a reference for possible applications of the system in the auxiliary diagnosis of bowel problems. et al.
