Electronics and Bioelectronic Interfaces

Abstract

Solution‐processed electronic materials have gained tremendous momentum in the application of electronics, photovoltaics, and catalysts for being vacuum‐free with rapid deposition on targeted substrates at an atmospheric pressure, large area with selective deposition via various printing techniques in addition to high electrical performances. However, despite their growing impact, the application in bioelectronics has been deterred for the development of future human‐friendly or implantable electronics. This is attributed to lack of underlying studies on their material properties and interfaces under the aqueous environments, which is a prerequisite condition to be tested before physiological application. In this chapter, we discuss two different types of emerging inorganic and organic electronic materials for potential application of bioelectronics, especially on sol–gel metal oxide semiconductors ( MOx ) and solution‐processed conducting polymers ( CP ), respectively.
