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

open access: yesAdvanced Materials Technologies, Volume 11, Issue 17, 3 September 2026.
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

A COMPREHENSIVE RESEARCH PAPER ON LITHIUM-ION BATTERIES- ADVANCES AND CHALLENGES OF BATTERY MANAGEMENT SYSTEMS (BMS)

open access: yes
Lithium-ion batteries (LIBs) have revolutionized the energy storage landscape due to their high energy density, long cycle life, and efficiency. Widely used in portable electronics, electric vehicles (EVs), and renewable energy systems, LIBs are pivotal in the transition to a low-carbon future.

Electrical‐Stimulation Hydrogel Electronic Skin for Sustainable Hybrid Biomechanical–Electromagnetic Energy Harvesting and Accelerating Wound Healing

open access: yesAdvanced Science, Volume 13, Issue 49, 3 September 2026.
A hybrid biomechanical–electromagnetic energy‐harvesting e‐skin is developed using a gelatin‐based outer matrix with a zwitterionic conductive inner layer. The e‐skin autonomously generates stable electrical stimulation from daily body motion and ambient electronics, enabling significantly enhanced wound healing bothin vitro and in vivo.

Metal Battery Anode: Rich in Electrons, Rich in Problems: A Critical Review from Industrial Perspectives

open access: yesAdvanced Science, Volume 13, Issue 49, 3 September 2026.
Metal‐anode batteries using Li, Na, Mg, and Ca offer exceptionally high energy density, but dendrites, unstable interphases, cracking, and pore formation hinder durability and safety. This review shows how careful electrolyte and interphase design can stabilize these reactive metals.

High‐Surface‐Area Carbon Nanotubes‐Copper Composite Foils for Lighter Advanced Anodic Current Collector for Lithium‐Ion Batteries

open access: yesAdvanced Energy and Sustainability Research, Volume 7, Issue 9, September 2026.
A fabrication method was developed produce MWCNTs/copper composite foil meeting industrial requirements for large‐area, thin, and advanced current collectors. The resulting material shows enhanced electrical properties with a decreased density compared to commercial copper foil.

Incidence of dementia and mild cognitive impairment in two Indigenous Bolivian cohorts

open access: yesAlzheimer's &Dementia, Volume 22, Issue 9, September 2026.
Abstract INTRODUCTION We studied dementia incidence and risk factors in Indigenous Tsimane and Moseten Amerindian populations in Amazonian Bolivia with largely subsistence lifestyles. METHODS A median of 4.7 years after baseline dementia assessment, 730 participants (52% male; mean age 67.3 years) were re‐visited at two follow‐up phases to determine ...

Female vulnerability to microvascular transport dysfunction emerges early across the Alzheimer's disease continuum

open access: yesAlzheimer's &Dementia, Volume 22, Issue 9, September 2026.
Abstract INTRODUCTION We tested whether quantitative transport mapping (QTM)‐derived perfusion velocity would detect earlier and more sex‐specific microvascular alterations than cerebral blood flow (CBF) across the Alzheimer's disease (AD) continuum.
