Hydroxyapatite, a bioceramic that mimics the mineral composition of bone, has attracted attention in both in vitro and in vivo settings for its excellent biocompatibility and osteoconductivity. Pure and magnesium-doped hydroxyapatite were synthesized using chemical method, and the samples were characterized using XRD, FTIR, and EDX. The dielectric constant, AC conductivity, dielectric loss, and capacitance of the samples were measured. The study of dielectric properties of hydroxyapatite-based materials for bioelectronics and smart biomedical devices has been a recent area of interest. Preliminary studies on the effect of these samples on the triboelectric performance of polyvinyl alcohol were also done. Magnesium is an essential trace element in human bones, and therefore, it was incorporated into the nanohydroxyapatite lattice to improve biological performance and electrical properties. The results indicate the tunability of electrical properties of nanohydroxyapatite and applications of magnesium–doped nanohydroxyapatite for future biomedical devices, sensors, and energy harvesting devices. |
