本文介绍了一种可吞咽的传感器装置，它可以口服，稍后到达胃，在那里该装置可以长期停留，并可以通过无线通信触发后随时排出。这种装置可以通过化学反应在胃肠道中给硅胶气球充气。气球在放气时可以用电解水的方法放气。为了减小传感器的体积，提出了一种基于化学反应的无电机排气方法。该装置可实现对胃肠道的长期监测。
This paper presents a swallowable sensor device that can be ingested orally, later arriving to the stomach, where the device can indwell for a long term and can be egested at any time after it is triggered using wireless communication. This device can inflate a silicone balloon in the gastrointestinal tract using a chemical reaction. The balloon can be deflated later using electrolysis of water at the time of egestion. A motorless chemical-reaction-based egestion method is proposed to minimize the sensor device size. This device can achieve long-term monitoring in the gastrointestinal tract.
