A wireless detection system for gastric pH based on edible and digestible materials

Abstract

The invention discloses a gastric pH wireless detection system prepared based on edible and digestible materials. The system includes a planar structure rolled into a cylindrical form, and a circuit pattern is printed on the surface of the planar structure. The circuit pattern includes a plurality of interdigital electrodes and an antenna part. The planar structure was rolled into a cylindrical form such that the interdigitated electrodes were on the outermost layer of the rolled planar structure. The rolled planar structure makes the antenna part in the circuit pattern into a coil shape.

Description

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS [0002] This application claims the benefit of US Patent Application Serial No. 62 / 632,545, filed on February 20, 2018, entitled "SWALLOWABLE, FOOD - BASED, DIGESTIBLE WIRELESS DEVICE FOR MEASURING GASTRIC pH)", which is hereby incorporated by reference in its entirety. Background technique [0003] Portable electronics, whether wearable or implantable, play an increasingly important role in healthcare monitoring, diagnosis and treatment. And with remarkable advancements in electronic materials—expanding form factors and compositions—and the advent of flexible, stretchable, and transient systems—has driven the development of healthcare devices. Skin-based systems can detect variables such as heart rate, temperature, and sweat-based body composition. Implantable systems can be more stable, but they are invasive, carry the risk of infection, bleeding, and require surgical recovery if they fail. [0004] The gastrointestinal (GI)...
