This chapter discusses the use of chitosan for sensors and electrochemical applications. The development of specific sensors and electrochemical devices is among the most innovative applications of chitosan and its composites and derivatives. These materials present characteristic chemical and electrical features, along with their interesting mechanical and biological properties (which have been extensively exploited before), making them unique materials for the referred applications. Although chitosan may present useful characteristics alone, many applications explore its use through chemical modifications or in composites, leading to materials that may present mixed characteristics or, in some cases, better performance due to synergic effects. This chapter will present how the structure of chitosan, whether alone or modified, as well as the composite materials containing this polymer, can present very interesting properties for its use in sensing platforms, solid‐state batteries, and other electronic devices.
