To obtain a high-performance extended gate field-effect transistor for pH detection, hafnium nitride (HfN) was first fabricated on an indium tin oxide polyethylene terephthalate (ITO/PET) substrate using high-power impulse magnetron sputter system (HiPIMS) in this study. It can be easily applied biomedical diagnostic and environmental monitoring applications with the advantages of flexible, disposable, cost-effective, reliable components. Various duty cycle conditions HiPIMSs were designed to investigate corresponding sensing performance material properties including surface morphology composition. As increased, grain size HfN increased. Additionally, X-ray photoelectron spectroscopy (XPS) analysis illustrated presence HfOxNy deposited surface. Both behaviors could result better based theory site-binding model. Subsequently, 15% exhibited excellent sensitivity linearity, values 59.3 mV/pH 99.8%, respectively; its hysteresis width drift coefficient -1 mV 0.5 mV/h, respectively. Furthermore, pH-sensing remained stable even after 2000 repeated bending cycles. These results indicate potential feasibility HiPIMS-deposited future wearable chemical applications.
