TL;DR: In this article, a multimode fiber specklegram sensor with a hetero-core fiber structure is used for displacement sensing, which is highly sensitive on the geometrical shape change of the sensing section.

TL;DR: In this paper, a dynamic electrooptic measurement carried out using a continuous frequency scan over the range of frequency covering the sample’s fundamental resonances was carried out and it was found that at certain frequencies relevant to piezoelectric resonance of a given mode, the E-field modulated optical transmission are greatly enhanced (> 2 orders of magnitude.

TL;DR: In this paper, a CFO-BTO (Cobalt Iron Oxide and Barium Titanate), ferromagnetic core and ferroelectric shell is modelled using COMSOL multiphysics simulation of 2.5mm and 5mm spherical radius that produced an electric pulse of 0.625µV of 8.33ms time scale when exposed to an external magnetic field of intensity 50 Oe at 60Hz.

TL;DR: In this article, temperature dependent piezoelectric properties of ferroelectric relaxor single crystals, particularly the cerium-doped strontium barium niobate compositions (SBN60: Ce), were investigated by resonance and anti-resonance technique.

TL;DR: In this paper, a modified single oscillator model was used to calculate the index of refraction in the ferroelectric phase and the deviation temperature from the single oscillators model was significant marking the crossover from macroscopic to microscopic polarization.
