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

Biodegradable Wireless Soil Urea Sensor Using Metamaterial Perfect Absorber for Distributed Deployment in Precision Agriculture

Advanced Materials Technologies, EarlyView.
In this study, we propose a biodegradable wireless soil urea sensor for precision agriculture. The sensor's electromagnetic response varies depending on the urea concentration, allowing the measurement of relative soil urea concentrations by analyzing the time‐transient electromagnetic response.

Lead‐Free Chiral Hybrid Metal Halides for Circularly Polarized Light‐Emitting Diodes

Advanced Optical Materials, EarlyView.
Lead‐free chiral hybrid metal halides provide a versatile platform for realizing chiroptical responses through chiral modulation of metal–halide frameworks with diverse dimensionalities, induces inversion‐symmetry breaking and enables dissymmetric excited‐state transitions toward efficient circularly polarized luminescence and electroluminescence. This

Temperature Correction in a Single Luminophore Pressure‐Sensitive Paint Using a Dual‐Emitting Gold Acridine Complex

Advanced Optical Materials, EarlyView.
The use of pressure‐sensitive luminescent molecules to quantify surface pressure in wind tunnel testing has revolutionized experimental aerodynamics. This work develops a dual‐emitting gold acridine complex for the simultaneous sensing of pressure and temperature independently of each other.

Directed Acyclic Graph-Based Blockchain Performance Analysis and Its Secure Operation in Opportunistic Networks

IET Software
Directed acyclic graph (DAG)-based blockchain is a promising paradigm of a blockchain system. During DAG-based consensus processes, nodes generate blocks in parallel, as well as voting YES on the previous blocks.
