A 400 MHz magnetoelectric (ME) Lamb wave antenna design to function in the medical implant communication service band is proposed. The employs a heterostructure of piezoelectric and magnetostrictive membranes acoustically excite standing shear bulk radiate as magnetic dipole. Multiphysics finite element analysis simulations are performed for transmission reception modes. In these simulations, three aspects investigated: piezoelectricity, micromagnetic precession, dipole radiation. An...
We investigate localized in-plane strains on the microscale, induced by arrays of biased surface electrodes patterned piezoelectrics. Particular focus is given to influence that adjacent electrode pairs have one another study impact densely packed arrays. present a series X-ray microdiffraction studies reveal spatially resolved micrometer-scale strain distribution. The maps with resolution highlight how local profile in square regions up 250 × μm2 size affected are ferroelectric...
Abstract A new device termed “Optomagnetic Micromirror Arrays” (OMA) is demonstrated capable of mapping the stiffness distribution biomimetic materials across a 5.1 mm × 7.2 field view with cellular resolution. The OMA comprises an array 50 000 magnetic micromirrors optical grating structures embedded beneath elastic PDMS film, affixed on top. Illumination broadband white light beam onto these results in reflection microscale rainbow rays each micromirror. When applied, it causes micromirror...
