In this study, a low-frequency instrumentation amplifier (LFIA) integrated with an extendedgate field-effect transistor (EGFET) is presented to realize the simplicity common source amplifier (CSA) structure. The proposed EGFET CSA was developed by the 0.18-μm CMOS process technology of Taiwan Semiconductor Manufacturing Company (TSMC). The EGFET CSA has low frequency and noise immunity function, and it can effectively output the response signal, with good stability and effectively improve the sensitivity, not susceptible to environmental factors, easy to replace, and low cost. Moreover, the simple circuit design of the EGFET CSA was used to analyze the sensing characteristics and to improve the stability of the ruthenium dioxide (RuO2) lactic acid (LA) biosensor. Therefore, the EGFET CSA is suitable for LA detection. The simple process of the EGFET CSA was used to analyze the sensing characteristics and to improve the stability of the ruthenium dioxide (RuO2) lactic acid (LA) biosensor. An arrayed potentiometric LA biosensor based on the RuO2 thin film was proposed and manufactured in this study. The experimental results indicated that the EGFET CSA as a low-frequency instrumentation amplifier has achieved a good sensitivity (53.41mV/mM) and satisfactory linearity (0.997) on the RuO2 LA biosensor as compared with the V-T measurement system.INDEX TERMS Extended gate field-effect transistor (EGFET), common source amplifier (CSA), ruthenium dioxide (RuO2), lactic acid (LA), low-frequency instrumentation amplifier (LFIA).

Developing electrocatalysts with excellent activity and stability for water splitting in acidic media remains a formidable challenge due to the sluggish kinetics and severe dissolution. As a solution, a multi‐component doped RuO2 prepared through a process of dealloying‐annealing is presented. The resulting multi‐doped RuO2 possesses a nanoporous structure, ensuring a high utilization efficiency of Ru. Furthermore, the dopants can regulate the electronic structure, causing electron aggregation around unsaturated Ru sites, which mitigates Ru dissolution and significantly enhances the catalytic stability/activity. The representative catalyst (FeCoNiCrTi‐RuO2) shows an overpotential of 167 mV at 10 mA cm−2 for oxygen evolution reaction (OER) in 0.5 m H2SO4 solution with a Tafel slope of 53.1 mV dec−1, which is among the highest performance reported. Moreover, it remains stable for over 200 h at a current density of 10 mA cm−2. This work presents a promising approach for improving RuO2‐based electrocatalysts, offering a crucial advancement for electrochemical water splitting.
