In this study, ReRAM devices for electro-chemical bio applications were developed, and a biotransducer with a threshold-sensing function using the ReRAM was developed for the first time. The fabricated Si CMOS-compatible ReRAM device exhibited an excellent on/off resistance ratio of 50 with high endurance compared to the previous results. The threshold-sensing function of the implemented bio-transducer was confirmed experimentally as intended for various pHs of 0 to 10. It was also possible to change the threshold point utilizing a voltage variable function in the circuit. It is expected that this technology can be used into high-density/low-power edge-type biosensors for various infectious diseases.
