Flexible memristors based on carbon quantum dots (CQDs) are explored in this study, representing a pivotal advancement in non-volatile memory technology within the realm of portable artificial intelligence. Leveraging the exceptional flexibility and stability of polyethylene terephthalate (PET) substrates, these devices demonstrate resistance switching characteristics akin to their initial state despite enduring multiple instances of destructive folding. Notably, analyses including current-voltage curve (I-V) assessments and long-term potentiation/long-term depression (LTP/LTD) evaluations reinforce this resilience. Furthermore, these devices exhibit classical synaptic behaviors, such as spike-timing-dependent plasticity (STDP), paired-pulse facilitation ( PPF ), and the transition from short-term memory (STM) to long-term memory (LTM). This research represents a significant stride towards the advancement of the next generation of flexible memory devices.
