Analysis of glucose‐dependent dielectric properties of aqueous‐based solution: A proof of concept
In spite of widespread research and exploration, the status of non‐invasive blood glucometer for diabetic people is far from satisfactory. This unlocks the prospect for further significant research in the field of non‐invasive blood glucose sensing.

Simple non-invasive measurement of complex permittivity
A simple non-invasive sensor measures complex permittivity at microwave (UHF) frequencies from changes in resonance frequency and reflection coefficient. Response to reference liquids is in good agreement with finite difference time-domain calculation.

Interaction‐Driven Assembly Pathways in Heterogeneous Active Microrobotic Systems
Peanut‐ and cube‐shaped light‐powered microrobots exhibit distinct magnetic and photocatalytic responses that determine their heterogeneous self‐assembly. In the dark, magnetic dipole interactions drive colloidal copolymerization with cubes acting as nucleation centers, whereas under light irradiation, phoretic interactions compete with magnetic ...

Complex Permittivity to Detect Lead in Soil with Various Salt Forms and Combinations
The response of soil-water systems to an external electric field can be described as polarization and conduction. Polarization represents the electric charges stored in a material, whereas conduction is the ability of a material to conduct free charges ...

core
Fiber‐reinforced liquid metal composites (FibRe LMCs) are introduced that combine GPa‐scale structural performance with digitally programmable electrical conductivity. Through automated CNC activation, conductive pathways and wireless power transfer circuits are fabricated directly within load‐bearing composites, enabling structurally integrated ...

Measured Dielectric Permittivity of Contaminated Sandy Soil at Microwave Frequency
Measurement of dielectric permittivity of soil has been studied by many researchers. However, few studies have been conducted on contaminated soil. The motivation of the present study is to investigate the behavior of sandy soil contaminated by lubricant

Dielectric spectroscopy of PETG/TiO2 composite intended for 3D printing
3D-printed electronics belong to new approaches to how to build a complex object with multiple desired functions. For that purpose, materials with specific electric properties are needed: conductors, insulators, magnetics, or dielectrics with high ...
