A Magnetically Coupled Piezoelectric–Electromagnetic Low-Frequency Multidirection Hybrid Energy Harvester

open access: yesMicromachines, 2022
The traditional single electromechanical conversion energy harvester can collect energy only in a single vibration direction. Moreover, it requires high environmental vibration frequency, and its output power is low.

A Piezoelectric and Electromagnetic Hybrid Galloping Energy Harvester with the Magnet Embedded in the Bluff Body

open access: yesMicromachines, 2021
To meet the needs of low-power microelectronic devices for on-site self-supply energy, a galloping piezoelectric–electromagnetic energy harvester (GPEEH) is proposed. It consists of a galloping piezoelectric energy harvester (GPEH) and an electromagnetic

Characterization of Induced Polarization Parameters from Electromagnetic Data using Evolutionary Approach [PDF]

open access: yesJournal of Electromagnetic Engineering and Science, 2023
Electromagnetic methods are one of the most important tools for exploring the physical properties of scatterers. When the scattering object is polarizable, more information can be gained from electromagnetic measurements to determine the scatterer’s ...

The untold saga of chromotherapy in dentistry

open access: yesJournal of Family Medicine and Primary Care, 2022
Being a centuries-old concept and used successfully over years, chromotherapy is the method of treating diseases using coloured food, coloured clothing, colour saturated oils, coloured water and visible spectrum of electromagnetic radiation. The basis of

Histories electromagnetism [PDF]

open access: yesJournal of Mathematical Physics, 2004
Working within the HPO (History Projection Operator) Consistent Histories formalism, we follow the work of Savvidou on (scalar) field theory [J. Math. Phys. 43, 3053 (2002)] and that of Savvidou and Anastopoulos on (first-class) constrained systems [Class. Quantum Gravt.

Electromagnetic circuits

open access: yesNetworks & Heterogeneous Media, 2010
The electromagnetic analog of an elastic spring-mass network is constructed. These electromagnetic circuits offer the promise of manipulating electromagnetic fields in new ways, and linear electrical circuits correspond to a subclass of them. They consist of thin triangular magnetic components joined at the edges by cylindrical dielectric components ...

Measurement and control systems for an imaging electromagnetic flow meter [PDF]

open access: yes, 2014
Electromagnetic flow metres based on the principles of Faraday's laws of induction have been used successfully in many industries. The conventional electromagnetic flow metre can measure the mean liquid velocity in axisymmetric single phase flows ...
