In this paper, the surveys on the stylus technologies for capacitive-type touch systems (CTSs) are presented. The stylus technologies are classified into the passive and active stylus depending on the battery integration. To explain two types of the stylus, the architecture of CTS with the stylus is firstly explained. Afterward, the operation principles of the passive, which have a capacitive-type (C-type), an electromagnetic resonance type, and an electrically coupled resonance type, and a C-type active type styli are described.
