Materials and Their Classifications in Bioelectronics

Bioelectronics searches for the union between living systems and electronic devices, which would allow understanding, monitoring, stimulating, and controlling electrical signals at a biological level, to advance in the diagnosis, treatment, and prophylaxis of diseases, as well as in the development of devices and tools to study the biological systems. The materials used for the manufacture of the bioelectronics devices are characterized by allowing charge transport between biotic and abiotic systems, being biocompatible, and having mechanical properties that facilitate their adjustment to the application. In this chapter, the classification of bioelectronics materials is presented, according to their composition as inorganic or organic, and according to their application as electronic materials to solve medicine and biology problems, materials for the use of biological systems in electronics, and materials to interface electronic devices with living systems.
