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 ...

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

All-optical switching via four-wave mixing Bragg scattering in a silicon platform

APL Photonics, 2017
We employ the process of non-degenerate four-wave mixing Bragg scattering to demonstrate all-optical control in a silicon platform. In our configuration, a strong, non-information-carrying pump is mixed with a weak control pump and an

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.

Reconfigurable logic gates driven by spatially designed excitation: Spectra manipulation the coupled random laser system

APL Photonics
All-optical logic gates offer ultra-fast speed information processing and lower power consumption that still misses the reconfigurability, remaining beset for high power consumption and large space requirements.

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 ...
