A unipolar-driven synaptic transistor for environment-adaptable vision system

The synapses in peripheral nerves of human eyes handle intensity-modulated unipolar input, different to the bipolar spike-driven modulation in artificial synapses. Jang et al. emulate this biological function in a single transistor device and implement it into a self-adaptive artificial vision system.

Highly parallel and ultra-low-power probabilistic reasoning with programmable gaussian-like memory transistors

Probabilistic inference hardware prevents overconfidence. Lee et al. report a Gaussian-like memory transistor using p-n junction coupled with separate floating gate, offering precise control of the Gaussian outputs, simplified circuit design, and low power consumption for inference computing.

Vertically stacked, low-voltage organic ternary logic circuits including nonvolatile floating-gate memory transistors

High-density information processing without increasing the circuit complexity is highly desired in electronics. Here, Im et al. demonstrate a low-voltage organic ternary logic circuit vertically integrated with the nonvolatile flash memory, increasing the information density by a factor of 3.

Label-free nanoscale optical metrology on myelinated axons in vivo

Spectral reflectance has been used to achieve label-free, in vivo imaging of myelin, a membranous sheath that allows faster electrical conduction along neuronal axons. Here the authors extend this technique to measure nanoscale features, including changes following traumatic brain injury.

Microsphere-based interferometric optical probe

Tagging and tracking cells with multiplexed labels can help study complex cellular behaviors in living systems. Here, Jo et al. propose and demonstrate the use of Fabry-Perot-like resonances in dielectric microspheres as such a label and call these reflectophores.

High-speed, scanned laser structuring of multi-layered eco/bioresorbable materials for advanced electronic systems

Designing and manufacturing eco/bioresorbable electronic systems remains a challenge. The authors introduce a picosecond-pulsed laser-based scheme that exploits controlled patterning, thinning, and/or cutting to manipulate multilayers of eco/bioresorbable materials for a wide range of advanced electronic systems.
