Traction Force Microscopy for Viscoelastic Substrates: A Semi‐Analytical Method

open access: yesAdvanced Science, EarlyView.
A semi‐analytical viscoelastic traction force microscopy framework is introduced for quantifying time‐resolved cell tractions on flat finite‐thickness substrates. The method generalizes elastic traction force microscopy to Generalized Maxwell materials, identifies when elastic approximations remain valid and, when they do not, shows that inferred ...

Advanced Technologies for Characterizing and Detecting Battery Thermal Failure: A Review

open access: yesAdvanced Science, EarlyView.
Illustration of advanced characterization techniques to predict battery thermal failure. ABSTRACT Energy storage is essential in accelerating the global transition toward clean and sustainable energy across various sectors. Lithium‐ion batteries (LIBs) have become increasingly significant for energy storage due to their high energy density, low ...

Manipulating Atomic Disorder and Mesoscale Architectures for High‐Efficiency Thermoelectric Modules

open access: yesAdvanced Science, EarlyView.
The in situ reaction of PbTiO3 precursor reacts in situ with the Bi0.5Sb1.5Te3 matrix, effectively enlarging the energy barrier for minority carrier excitation and suppressing bipolar diffusion, and predominantly scattering mid‐to‐low frequency phonons. Ultimately, a single thermoelectric module was fabricated to achieve a competitive efficiency of ∼7%

A Large‐Area Broadband Multimodal Dual‐Resonant Haptic Device for Bidirectional Telerobotic and Augmented Interactions

open access: yesAdvanced Science, EarlyView.
We present a large‐area bidirectional human–machine interface integrating electrostatic multimodal tactile sensing with a dual‐resonant haptic actuator. The system enables linear pressure sensing that is decoupled from actuation and stable broadband vibrotactile feedback under dynamic contact conditions, supporting real‐time feedback modulation aligned

Flexible IMU Sensor Array For 3D Colonoscope Shape Reconstruction and AI‐Based Loop Detection

open access: yesAdvanced Science, EarlyView.
We propose a sensing platform for 3D visualization of the colonoscope combined with artificial intelligence (AI)‐based loop detection. The system consists of an array of 15 inertial measurement units (IMUs) mounted on a flexible printed circuit board that can be retrofitted into the instrument channel of conventional colonoscopes.

High‐Power Terahertz Emission from Picosecond Nano‐Plasma Switching Driven by Secondary Electron Emission Avalanche

open access: yesAdvanced Science, EarlyView.
A nano‐plasma device enables watt‐level on‐chip THz generation through picosecond switching triggered by secondary electron emission avalanche. An ultra‐dense electron sheet initiates nano‐plasma formation within a ∼100 nm gap, driving rapid energy release into an integrated resonator.
