Laser-Induced Graphene-Based Potentiometric pH and Nonenzymatic Uric Acid Sensors for Urine Analysis on Baby Diaper
Abstract
High Resolution Image Download MS PowerPoint Slide The fabrication of wearable sensors and their integration into real devices is an emerging demand in the field of sensor development. In this work, flexible sensors based on laser-induced graphene (LIG) were developed using a low-cost visible laser on polyimide tape for pH and uric acid monitoring in urine. A potentiometric pH sensor was fabricated by modifying the LIG surface with polyaniline, achieving a sensitivity of 56.7 ± 2.6 mV/pH across a wide pH range (4–10) with a rapid response time of
