Abstract Ingestible sensors are pivotal in monitoring the gastrointestinal (GI) tract and enhancing comprehension of complex gastrointestinal processes, propelled by sensor technology advancements. They must ensure robust wireless communication from deep within the body while maintaining longevity for comprehensive monitoring. Wireless system miniaturization stands as a promising solution to these challenges. This paper introduces the current state and technical challenges ingestible sensors and their solutions for wireless system miniaturization. The key techniques for further miniaturization include the antenna miniaturization, integration of adaptive impedance matching networks, and the replacement of crystal. Additionally, the paper explores future directions for wireless communication systems to support the continued advancement of ingestible sensor technology.
