What Is Edible Electronics
Edible electronics refer to a class of electronic devices or components designed to be consumed or integrated into ingestible products, compatible with the human digestive system. These devices utilize biocompatible materials and encapsulation techniques, ensuring they pose no harm upon ingestion. Often leveraging biodegradable substrates, they serve applications ranging from medical diagnostics to personalized health monitoring. Edible sensors and actuators can transmit vital physiological data, allowing for real-time health assessment. This emerging field holds immense potential for revolutionizing healthcare, as it offers non-invasive, patient-friendly monitoring solutions, and paves the way for a new frontier in bioelectronic medicine.
