Bioinspired Twisted Artificial Muscles with Enhanced Performance for Underwater Applications

Advanced Science, EarlyView.
A climbing plant‐inspired twisted artificial muscle (TAM) with a braided configuration and seal‐inspired thermal insulation enables high‐performance underwater actuation. Enhanced deformation, reduced heat dissipation, and rapid motion are validated through a bionic ray that exhibits straight and turning motions.

Robust Physics‐Informed Neural Network Approach for Estimating Heterogeneous Elastic Properties from Noisy Displacement Data

Advanced Science, EarlyView.
Heterogeneous distributions of elasticity parameters are learned from noisy displacement data using the Inverse Elasticity Physics‐Informed Neural Network (IE‐PINN). This approach integrates both data‐driven and physics‐driven methods to address the significant limitations faced by existing techniques.

Analyzing the Profile Effects of the Various Magnet Shapes in Axial Flux PM Motors by Means of 3D-FEA

, 2018
Axial flux machines have positive sides on the power and torque density profile. However, the price of this profile is paid by the torque ripples and irregular magnetic flux density production.

Synergistic Anti‐Cancer Therapy Through Ultrasound‐Induced Piezocatalytic Therapy and Tumor Treatment Fields

Advanced Science, EarlyView.
A novel, wearable anti‐cancer platform synergistically combines tumor treating fields (TTFs) and piezocatalytic therapy (PCT) via ultrasound‐activated, lead‐free piezocomposites. This strategy efficiently suppresses tumor growth, modulates the immune microenvironment, and demonstrates strong therapeutic synergy in both mouse model of subcutaneous tumor
