Demonstration of CMOS-compatible memristor-based electrochemical biosensor transducer with threshold-sensing functionality.

ABSTRACT: Many electrochemical biosensors operate based on a threshold-sensing (TS) method, which indicates the presence of a disease when the concentration of a biomarker exceeds a predetermined, disease-specific threshold. The TS in biosensor systems is often implemented using power-hungry signal processing (SP) modules or computers, which increases energy consumption and system complexity. Here, we propose a memristor-based bio-to-electrical transducer with built-in TS functionality, allowing TS to be performed directly within the transducer instead of relying on SP modules and computers. Fabricated resistive random-access memory-based TaO_X/Ta₂O₅ memristors meet the transducer requirements, such as a high on/off ratio greater than 30 while maintaining a long unit
