Abstract
Researchers at Purdue University have created waterproof electronic decals (WPEDs) which are flexible electronic devices capable of continuously monitoring pH levels of biofluids wirelessly. The devices are fabricated on biocompatible materials and are lightweight, breathable, flexible, and easy to apply. The devices use a polyaniline/silver composite to measure a wide range of pH, covering the clinically relevant ranges of most biofluids. WPEDs can be worn on the skin to stimulate sweat and measure sweat pH, or be attached to the surface of sanitary tampons to detect bacterial vaginosis by monitoring vaginal pH.
