  • A two-terminal self-rectfying TaOy/Nanoporous TaOx memristor synapse was fabricated based on anodization process. The device exhibits high non-linearity, low synapse-coupling (S.C), acceptable endurance, sweeping and retention stability, as well as essential synaptic functions such as long-term plasticity and spiking-timing-dependent-plasticity. Furthermore, crossbar array consisting of the only designed device without any selector shows relatively well-defined switching parameters with acceptable cell uniformity and capability of suppressing undesired pathways. The effect of S.C on recognition accuracy of MNIST patterns was also simulated for the first time. Based on experimental average S.C value, the device exhibited the high accuracy comparable to S.C = 0

  • In-sensor computing minimizes latency by directly processing data at the point of capture. Here, authors optimize this process by integrating polarization-sensitive detectors into the computing framework, enabling the superposition of two filtering operations within a single circuit.

  • A tactile visual artificial synapse provides a route for in situ health monitoring. Here the authors report an electrochemical transistor comprising a top gate as a tactile receptor and a light-emitting ion gel layer stacked on a polymeric semiconductor to monitor finger motions and heartbeats.

  • A wide reservoir computing system is an advanced architecture. However, its hardware implementation remains elusive due to the lack of 3D architecture framework. Choi et al. demonstrate such hardware made of a multilayered 3D stacked memristive crossbar array for efficient learning and forecasting.

  • Molecular electronics holds promise for device miniaturization yet can only be realized by choosing specially designed molecular species to date. Here, Shin et al. show tunable rectifying characteristics in a molecular heterojunction with non-functionalized molecules and two-dimensional semiconductors.
