Multiomics identifies the link between intratumor steatosis and the exhausted tumor immune microenvironment in hepatocellular carcinoma

Hepatology, EarlyView., 2022
Steatotic HCC can be diagnosed by MRI and forms a pro‐tumor immune microenvironment with high expression of PD‐L1, M2 polarization of macrophages and activation of CAFs, which may be a good target for combined immunotherapy. Abstract Background and Aims Immunotherapy has become the standard‐of‐care treatment for hepatocellular carcinoma (HCC), but its ...

Soft Skins With Reversible Thickness Morphing: Materials, Mechanisms, and Applications

Advanced Materials, EarlyView.
Evolution of electronic skin (e‐skin) technologies toward adaptive, multifunctional soft skins. Phase I highlights early rigid and discrete sensory interfaces. Phase II shows the transition toward flexible, stretchable, and large‐area e‐skin. Phase III captures the emergence of computational e‐skin.

Fiber Bragg Grating Pressure Sensor Integrated with Epoxy Diaphragm

Sensors, 2021
A fiber Bragg grating (FBG) sensor integrated with an epoxy diaphragm was developed for the measurement of pressure and water level. The bending strain of a circular diaphragm induced by uniform pressure was transferred to the FBG sensor. The response of

Ultrathin Hydrogel Membranes Inspired by Soap Films Enable Physiologically Relevant Breathing Lung Models

Advanced Materials, EarlyView.
A soap‐film inspired strategy enables the fabrication of ultrathin yet robust GelMA‐PAAm membranes for breathing lung culture. The hydrogel membrane supports long‐term cyclic deformation under air‐liquid interface conditions, enabling physiologically relevant breathing motions of engineered lung tissue culture. ABSTRACT Breathing continuously stretches

Testing and Simulation of Multilayer Polyvinylidene Fluoride‐Based Piezoelectric Energy Harvester Devices

Advanced Materials Technologies, EarlyView.
The study considers the use of polymer/dielectric‐based multilayers piezoelectric Energy Harvesters (EH) to produce an output voltage and current, by exploiting the mechanical energy provided by human organs movements. In particular, the heart motion is considered from the kinematic viewpoint, and a multiphysics theoretical model is developed to assess

Compliant Pneumatic Feet with Real‐Time Stiffness Adaptation for Humanoid Locomotion

Advanced Robotics Research, EarlyView.
A compliant pneumatic foot with real‐time variable stiffness enables humanoid robots to adapt to changing terrains. Using onboard vision and pressure control, the foot modulates stiffness within each gait cycle, reducing impact forces and improving balance. The design, cast in soft silicone with embedded air chambers and Kevlar wrapping, offers durable,
