Key Points:
- Ingestible sensors, which originated from capsule endoscopy technology, have evolved significantly. Advances in miniaturization, biocompatibility, and wireless communication have moved these devices from science fiction to practical medical tools.
- These sensors are small enough to be swallowed and travel through the digestive tract. They are composed of a sensor module for collecting data, a data transmission module for wireless communication, and a power source, usually a small battery. The casing is made from biocompatible materials to ensure safety and effectiveness throughout their journey in the body.
- Ingestible sensors can monitor various physiological parameters like temperature, pH levels, and biomarkers, providing real-time data that helps in the diagnosis and management of gastrointestinal conditions such as IBD, gastrointestinal bleeding, and motility disorders.
