(a) Current–voltage characteristics of the device at a relative humidity of 45%. The voltage sweep direction (0 → 2 → −2 → 0 V) is displayed with navy arrows. (b) Current humidity characteristics of the device with a constant read voltage of 0.3 V. The RH sweep direction (5 → 95 → 5%) is displayed with navy arrows. (c) Data retention characteristics of the device in voltage mode (top) and RH mode (bottom). (d) The current variation of the Y7C peptide memristor controlled by voltage and/or RH input, clearly showing bimodal operation. Voltage pulse, RH pulse, and current output are represented by red, blue and green curves, respectively.
