需要新的研究和诊断工具来持续测量肠道状态和活动。我们研究了几种传感器的体内和体外功能。测试了五种传感器类型，包括压力、红外、颜色、电导率和电容，以验证结肠内的功能。最初的有线原型在台式测试中进行了测试和校准，然后在三个急性外科手术中将其插入猪结肠和直肠管腔内。台式和体内测试的结果相互关联并表明压力、电导率和电容测量可以提供有关肠道状态及其活动的信息。
New research and diagnosis tools are needed to continuously measure bowel state and activity. We investigated functionality of several sensors in vivo and in vitro. Five sensor types, including pressure, infrared, color, conductivity and capacitance, were tested to validate functionality inside the colon. Initial wired prototypes were tested and calibrated in benchtop testing and then inserted intraluminally into pig colon and rectum in three acute surgical procedures. The results from both benchtop and in-vivo testing correlate and indicate that pressure, conductivity, and capacitance measurements could provide information on the state of the bowel and its activity.
