Laser Ultrasound Super‐Resolution Imaging for Multi‐Parametric Non‐Invasive Volumetric Characterization of Brain Cancer

open access: yesAdvanced Science, EarlyView.
Laser ultrasound super‐resolution imaging (LUSSI) leverages laser‐generated ultrasound for functional 3D transcranial imaging of brain tumor vasculature. Combined with optoacoustic tomography, it is demonstrated in a glioblastoma model, revealing structural abnormalities, compressed vessels, hemorrhages, and hypoxic regions.

A Resistive Soft Robotic Exosuit for Dynamic Body Loading in Hypogravity

open access: yesAdvanced Science, EarlyView.
The resistive hypogravity exosuit is a lightweight wearable robotic exosuit that uses pneumatic artificial muscles to restore Earth‐like metabolic and muscular demands during locomotion in low gravity. Tested on healthy subjects in Earth and simulated Moon gravity, the suit restores energy expenditure and muscle activation without altering gait ...

Inverse Co‐Design of Mechanical And Sensory Properties in Soft Lattice Foams for Multifunctional Wearables

open access: yesAdvanced Science, EarlyView.
An inverse co‐design framework integrates neural networks and physics‐based models to engineer soft lattice foams with independently tunable mechanical and sensory properties. By layering architected foams and optimizing electrode placement, this method enables multifunctional wearable sensors.

Edible Pneumatic Battery for Sustained and Repeated Robot Actuation

open access: yesAdvanced Science, EarlyView.
This work presents an edible energy source and valve system to power soft, pneumatically driven edible robots. A chemical reaction between sodium bicarbonate and citric acid generates carbon dioxide gas, and a pressure‐triggered edible valve enables self‐repetitive motion of the edible actuator.

Are rigid non-inertial frames of reference really rigid?

open access: yes, 2013
In this paper the notion of the rigid frame of reference within special relativity is analysed. Three definitions of rigidity are formulated. By using several examples of non-inertial frames, it is shown that these definitions are not equivalent. It is also shown that so called M ller rigid non-inertial frames are locally rigid, but do not exhibit ...

Learning to Navigate in Chemical Fields Without A Map at Low Reynolds Numbers

open access: yesAdvanced Science, EarlyView.
Deep reinforcement learning enables a reconfigurable artificial microswimmer to exhibit run‐and‐tumble strategy to navigate toward a chemical source. This mapless microswimmer can robustly navigate in diverse chemical fields without relying on a pre‐existing map.
