The invention relates to a self-driven friction nano-generation synaptic
transistor. The synaptic
transistor comprises a friction nano-generator and a synaptic
transistor, and further comprises: a substrate; an
electrode layer formed on the substrate; a shared intermediate layer formed on the
electrode layer; a synaptic transistor
active layer, a source
electrode and a drain electrode which formedon the shared intermediate layer; and a positive friction layer and a negative friction layer which are formed on the shared intermediate layer. The shared intermediate layer serves as a
dielectric layer of the synaptic transistor and an intermediate layer of the friction nano-generator, the output
voltage of the friction nano-generator is increased, the
synaptic function of the synaptic transistor can be realized, the electrode layer is used as an output electrode of the friction nano-generator and a gate electrode of thesynaptic transistor, is simple in structure, light and flexible, and rubs the positive friction layer or the negative friction layer, and the shared intermediate layer generates
pulse voltage, generates excitatory post-
synapse current between the source electrode and thedrain electrode without external power supply, and realizes a bionic synaptic transistor function through self-driving.
