Optimization and performance improvement of an electromagnetic-type energy harvester with consideration of human walking vibration
In this study, we derived an equation of motion for an electromechanical system in view of the components and working mechanism of an electromagnetic-type energy harvester (ETEH). An electromechanical transduc...

Magnetic-field-dependent shear modulus of a magnetorheological elastomer based on natural rubber
A magnetorheological elastomer (MRE) is a smart material that has a reversible and variable modulus in a magnetic field. Natural rubber, which has better physical properties than silicone matrices, was used as...
