Barium titanate, perovskite structure is known for its high dielectric constant and piezoelectric properties, which makes it interesting material for fabricating capacitors, transducer, actuator, and sensors. The perovskite crystal structure and lattice vibrations play a crucial role in its piezoelectric and ferroelectric behavior. In the present study, the barium titanate powder was subjected to biofield treatment. Further, the control and treated samples were characterized using X-ray diffraction (XRD) and Fourier transform infrared spectrometer (FT-IR) and Electron spin resonance (ESR). The XRD analysis showed the permanent compressive strain of 0.45% in treated barium titanate powder as compared to control. Furthermore, the biofield treatment had enhanced the density upto 1.38% in barium titanate as compared to control. The FT-IR spectra showed that the stretching and bending vibrations of Ti-O bond in treated BaTiO3 were shifted towards lower frequency as compared to control. The bond length was substantially increased by 0.72 % in treated BaTiO3 as compared to control. The ESR spectra of control and treated BaTiO3 sample showed the g-factor of 2.0;and biofield treatment has substantially changed the width and height of ESR signal in treated BaTiO3 as compared to control. These observations revealed that biofield treatment has significantly altered the crystal structure, lattice strain,and bond vibration of barium titanate.
In summary, the biofield treatment has induced the permanent compressive lattice strain in tetragonal crystal structure of BaTiO3, which may occur due to electromagnetic field transferred through biofield treatment. This permanently strained crystal structure of BaTiO3 led to alter its piezoelectric behavior. The FT-IR analysis result revealed that Ti-O bond length in BaTiO3 was increased by 0.72% after biofield treatment as compared to control. Therefore, these findings indicate that biofield treatment may be acting at atomic level of BaTiO3 to cause these modifications. Furthermore, the variation observed in width and height of ESR spectra, which suggest that particle size of treated BaTiO3 might be altered through high energy milling process. Hence, it is hypothesized that biofield treatment has induced the electric and magnetic field that can affect the BaTiO3 powder at electronic and atomic level. To conclude, the biofield treatment could be applied to alter the crystal structure and piezoelectricity of BaTiO3 powder.
