Resistive switching memory integrated with amorphous carbon-based nanogenerators for self-powered device

Memristor with low power consumption, high storage density and fast programming/erasing speed presents the promising applications ranging from terabit nonvolatile storage devices, memory-in-logic algorithmic chips and bio-inspired artificial neural network systems. However, memristor as a passive electronic device has to be driven by external bias voltage. To solve this issue, the flame synthesis carbon-based nanogenerators (Carbon-NGs) triggered by water evaporation at room temperature have shown a favorable open-circuit voltage of ~1.0 V and short-circuit out current of ~100 nA. Three Carbon-NGs connected in series are enough to driven the carbon memristor to work. States including the HRS, LRS, SET and RESET are obtained from the Ag|a-Carbon|Ag memristor driven by the Carbon-NGs cells. Therefore, a self-powered system is realized by the Carbon-NGs and memristor. This work provides an insight into the memristor self-powered system in terms of green materials, natural energy harvests and nano energy applications.
