Overview

Laboratory study reveals uncooled ultraviolet-to-infrared neuromorphic vision in graphene-coated pyroelectric devices, suggesting a scalable route toward energy-efficient thermal sensing systems.

Key Points

To develop an uncooled optoelectronic synaptic device that unifies detection, memory, and preprocessing across the ultraviolet to long-wave infrared spectrum within a single system.
Fabricated an uncooled optoelectronic synapse by coupling a monolayer graphene charge reservoir with a pyroelectric Pb[(Mg1/3Nb2/3)0.7Ti0.3]O3 (PMNPT) substrate.
Characterized excitatory postsynaptic currents, synaptic plasticity, and multispectral detection from ultraviolet up to 11.6 μm at room temperature without external cooling.
Implemented combined optical and electrical modulation to demonstrate adaptive gain control, associative learning, and an all-weather neuromorphic vision framework.
Demonstrated stable and repeatable excitatory postsynaptic currents with tunable short- and long-term plasticity at room temperature for wavelengths extending to 11.6 μm.
Achieved broad ultraviolet-to-infrared multispectral sensing, adaptive gain control, associative learning, and learning–forgetting–relearning dynamics in a single device.
Successfully realized an integrated neuromorphic vision system providing all-weather perception and memory-assisted multispectral image preprocessing.
