Voltage-controlled programmable polymer memory enabled by interface nanoengineering for thermal recognition recording

Abstract

Here, we report an artificial thermal recognition memory system mainly consisting of programmable polymer memristors and resistive temperature detectors. The memristor has a two-terminal structure with an insulating polymer sandwiched between a nanowrinkled graphene electrode and a nanopillar metal electrode, exhibiting novel voltage-controlled programmable rewritable and nonerasable nonvolatile memory effects. The integrated system is capable of detecting diverse weak and strong thermal stimuli and encoding them into binary memory signals for the selective recording of human thermal perception recognition. This work offers an effective strategy for constructing programmable memristive devices via interfacial nanoengineering and provides a new architecture of recognition memory for artificial intelligence.
