All-Optical Logic Gates Devices based on SPP Coupling between Graphene Sheets

Journal of Microwaves, Optoelectronics and Electromagnetic Applications
The aim of this work is to propose all-optical logic gates based on surface plasmon polaritons (SPP's) coupling among spatially separated graphene sheets. This model consists of graphene nanoribbons embedded in silica (SiO2) substrate place in a distance

Multifunctional Vertical Bulk-Heterojunction Transistors With Amorphous GaO_x for Neuromorphic Perception-to-Decision. [PDF]

Adv Sci (Weinh)
A multifunctional vertical bulk‐heterojunction transistor (MVBT) with amorphous GaOx integrates four functionalities within a single neuromorphic device. Gate‐source operation enables 254 nm deep‐ultraviolet sensing and threshold neuronal firing, whereas three‐terminal operation supports broadband UV–vis‐NIR synaptic functions and bias‐controlled ...

All-optical logic gates based on photoinduced anisotropy of bacteriorhodopsin film

, 2012
All-optical logic gates based on photoinduced anisotropy of bacteriorhodopsin (BR) film are proposed. The photoinduced anisotropy in BR film, which arises from the selective absorption of BR molecules to polarized light, can be controlled by changing the

Toward Perception‐Native Electronic Skin: Bio‐Inspired In‐/Near‐Sensor and Neuromorphic Computing for Humanoid Robots

Advanced Materials Technologies, EarlyView.
Dense tactile streams from across the humanoid body converge on collide in a central wiring and data bottleneck. By relocating computation closer to and then into the skin itself, near‐ and in‐sensor architectures, together with neuromorphic computing, chart a path toward perception‐native electronic skin, in which the conversion of stimulus into ...

Microscale 3D‐Printed Digital Strain Switches for Embedded Mechanical Computation

Advanced Materials Technologies, EarlyView.
Microscale 3D‐printed strain switches on flexible films convert deformation into native digital signals at geometry defined thresholds. A closed form model predicts switching from 3000 to 15 000 microstrain and is validated across 110 devices. Reliable ohmic closure and strain activated AND, OR, and XOR logic point toward low‐power mechanical ...

Full-Optical Logical Gates for Optical Signal Processing

Advances in Electrical and Electronic Engineering, 2008
This paper is dedicated to full-optical logical NOT, AND and NAND gates. In the first section are described logical functions based on Mach-Zehnder interferometric structure. The second part deals with full-optical logical gate AND, that utilizes TOAD structure. The last one is focused on the exploitation of logical gate AND for optical head separation

Multimodal Human–Robot Interaction Using Human Pose Estimation and Local Large Language Models

Advanced Robotics Research, EarlyView.
A multimodal human–robot interaction framework integrates human pose estimation (HPE) and a large language model (LLM) for gesture‐ and voice‐based robot control. Speech‐to‐text (STT) enables voice command interpretation, while a safety‐aware arbitration mechanism prioritizes gesture input for rapid intervention.

High-speed optical-optical logic gate for optical computers

Electronics Letters, 1985
A laser diode having a saturable absorber within its cavity is proposed as an optically triggered optical logic gate. A threshold characteristic, a small delay time, a short output pulse and a possibility of integration of the gate lasers are predicted by theoretical analysis.

Push the Limits: Human‐Like Multimodal Extreme Embodied Intelligence for Autonomous Racing

Advanced Robotics Research, EarlyView.
Autonomous racing tests embodied intelligence under extreme control limits of speed, actuation, and decision‐making. Inspired by human multimodality, we present Apex, an embodied agent deployed on a super‐formula racing car at Yas Marina. Integrating physics‐informed perception, multimodal learning, and tasking, Apex cuts lap times by 15% and achieves ...
