Advanced Biocompatible Piezoelectrics: Synthesis, Characterization, and Applications

Biocompatible piezoelectronics is an emerging field that focuses on the development and application of piezoelectric materials capable of converting mechanical strains into electric charges within the human body. These materials hold significant potential for activating biological processes, stimulating healing, powering implanted medical devices, and enabling artificial muscle functionality. However, conventional inorganic piezoelectrics are often rigid, brittle, and contain toxic elements, making them unsuitable for biomedical applications. Similarly, synthetic piezoelectric polymers like polyvinylidene difluoride (PVDF) fall short in terms of flexibility and biodegradability. Recent studies have explored novel biocompatible materials, such as those based on amino acids, peptides, and organic-inorganic hybrids, but there remains a need for further research to enhance their piezoelectric response and integration into advanced electronic systems.

This research topic aims to consolidate the latest advancements in the development of biocompatible materials with superior piezoelectric, mechanical, optical, and electrical properties, and their applications in the biomedical field. The primary objectives include addressing specific questions related to the synthesis, characterization, and application of these materials. Hypotheses to be tested may involve the efficacy of new materials in various biomedical applications, such as neuron repair, skin recovery, energy harvesting, and biosensing. By bringing together contributions from materials scientists, biomedical engineers, and nanotechnologists, this research topic seeks to drive progress in biocompatible piezoelectronics and pave the way for next-generation medical devices.
