本文提出了一种可吞咽的传感器设备，可以口服摄入，然后传递到胃，在那里该设备可以长时间驻留。使用无线通信，它可以在触发后的任何时间退出。该器械可使用硅胶球囊留置在胃肠道中。化学反应使胃内的气球膨胀。然后，使用具有电解水的致动器使传感器装置放气。用于具有电解的致动器的能量可以无线馈送。近场通信和柔性天线用于馈电和无线数据通信。由于柔性球囊和柔性天线，可以在不降低性能的情况下最小化设备尺寸。
This paper presents a swallowable sensor device that can be ingested orally, later passing to the stomach, where the device can indwell for long periods. Using wireless communication, it can be egested at any time after it is triggered. This device can indwell using a silicone balloon in the gastrointestinal tract. A chemical reaction inflates the balloon inside the stomach. Then it is deflated to egest the sensor device using an actuator with electrolysis of water. Energy for the actuator with electrolysis can be fed wirelessly. Near field communication and a flexible antenna are used for power feeding and wireless data communication. Because of the flexible balloon and the flexible antenna, the device size can be minimized without performance degradation.
