In this work, we approached sintering and crystallization of soyabean powders with a “cold sintering” approach to develop a bioelectret for potential high-frequency communication applications. Structural disintegration and phase evolution of glycinin globulin proteins present in soyabean powders in relation to sintering parameters were investigated using X ray diffraction (XRD), Fourier transform infrared (FTIR) spectroscopy, and thermogravimetry analysis (TGA). Piezoresponse force microscopy (PFM) showed some localized area with weak (0.7 pm/V) to reasonable (2.7 pm/V) out of plane piezoresponse in cold pressed and sintered soyabeans, respectively. Sintered bioelectrets did not show any macroscopic piezoelectricity, however.

Peptide nanotubes (PNTs) are bioelectrets that exhibit piezoelectricity, pyroelectricity, ferroelectricity, and birefringence. Birefringence is an optical property that can be used to determine the degree of order, orientation, size, and shape of PNTs. In this work, a custom-built optical apparatus is used to quantitatively measure birefringence in three dimensions of PNTs under varying electric fields and temperature. This work also includes techniques for aligning and orienting PNTs and discusses the role of birefringence measurements in the study of PNTs.

The study focuses on the synthesis of thermoelectrets by combining epoxy oligomer, epoxy-urethane modifier (PEF-3A), and polyaminoamide curing agent (L-20) and the influence of the modifier and curing agent on electret properties and mechanical strength. The process involves polymer synthesis through curing the initial oligomer and modifier, as well as polarization in a constant electric field to create the electret state of the polymer dielectrics. The variation of the content (2.5–10.0 wt.%) of the modifier in the composition results in changes in the electret and mechanical characteristics, including surface potential, effective surface charge density, electrostatic field strength, and Shore D hardness. These changes are attributed to the interplay between reduced mobility of polar groups due to strong physical intermolecular interaction in the structure of the network of the 3-D polymer and an increased number of functional groups participating in polarization processes. Increasing the content of modifier PEF-3A in the composition of the basic oligomer DER-331 leads to a decrease in the frequency of the spatial mesh of the resulting 3-D structure due to the incorporation of an epoxy-urethane oligomer with a large molecular weight. The study of DER-331 and L-20 composite by the method of thermally stimulated depolarization (TSD) reveals the process of polymer devitrification and the occurrence of post-curing reactions. The dielectric spectroscopy method proves the dipole macromolecular group orientation of epoxy polymer material, typical for the electret state of polymer dielectrics. According to the calculation data of dielectric relaxation process activation energy, it is concluded that the electret state in the polymeric matrix formed during curing and fixed by the chemical bonds of a 3-D network is a free state of epoxyamine macromolecules. Dipole groups, mostly oriented in one direction, are “frozen” in the cured net structure, acting as thermoelectret charge carriers. An increase in the modifier content does not significantly impact hardness, while polarization results in a marked difference between the Shore D hardness of unpolarized and polarized samples. This difference can be attributed to the orientation of polar groups during the synthesis, which leads to the emergence of a denser mesh of physical bonds. Therefore, by changing the formulation of the epoxy composition, it is possible to regulate its electret and strength properties.

Partial discharge (PD) monitoring presently emerged as an effective tool for condition monitoring of high voltage power apparatus. For high-voltage (HV) applications, fiber optic-based sensing has several advantages over conventional sensors requiring an electrical connection. Many fiber optic-based sensors are recently being proposed utilizing fiber Bragg grating, Sagnac effect, and interferometric principal for the PD monitoring of HV power apparatus that detects the acoustic wave generated from the occurrence of PD. This article presents an intensity-modulated fiber optic sensing principle that provides a more simplistic approach toward acoustic wave detection, as it does not require any specialized light source and detector. The PD is a stochastic natural phenomenon, and monitoring of PD demands high bandwidth in the high-frequency region so that low-frequency machinery noises are discarded. In this work, a fixed-fixed beam type structure that approximately resembles the characteristics of a bandpass filter has been designed from the first principal model equations. Then, an optical fiber-based secondary sensing element is used to convert the beam vibration into a light intensity that can be transmitted to monitoring stations at a long distance from the HV apparatus. The simulation-based study and its experimental verification reveal that the sensor can provide the required sensitivity and bandwidth in the high-frequency region for monitoring PD inside the HV power apparatus. Therefore, the proposed advanced PD sensor can be utilized for condition monitoring of electrical insulation.
