In previous research work related to the acoustic sensors, the researchers had focused on the individuality of the sensors for aeroacoustic application and sensors for audio range application. This paper describes a simple and novel model of acoustic sensor for aeroacoustic and audio applications (microphone). The model of the device presented in this paper shows interoperability. The sensor reported...
Ferroelectric and piezoelectric properties of lead-free BaTiO3 (BT), Ba0.92Ca0.08TiO3 (BCT8) and Fe doped (∼ 1.25, 1.5 and 2 wt. %) BCT8 electroceramics prepared by solid state reaction have been studied. X-ray diffraction results confirm the formation of tetragonal crystal lattice symmetry. All the samples exhibit typical polarization-electric field (P-E) hysteresis loop as well as strain-electric...
