Printed pH Sensors for Textile‐Based Wearables: A Conceptual and Experimental Study on Materials, Deposition Technology, and Sensing Principles

Abstract: Human biofluids contain numerous known physical and chemical biomarkers that play a vital role in diagnosing the human's health status. In healthy conditions, these biofluids maintain a strict pH balance with an efficient regulation, and slight changes in pH can be used as an early detector of malfunction or disease. Sweat is such a biofluid and normal sweat has a pH in the range of pH 4.5-6.8. [1] It is possible to track dehydration [2,3] or risk of diabetes [4] and detect cystic fibrosis [5] with the pH read… Show more

“…The as-fabricated electrodes are found to be more stable than previously reported anthraquinonesulfonate modified glassy carbon electrodes (2 months), cysteic acid/GO composite film (storage life-1 month), MWCNT/alizarin/Nafion (1 week), and carbon/PANI electrodes which exhibit stable results for 60 min. [60][61][62][63] Additionally, unlike glass bulb electrodes, these electrodes don't require any special storage conditions.…”
