Materials and the various properties associated with materials are the essential core of electrical engineering. Conductivity and resistance are essential electricity's flow and control, and various materials are better suited for the task than others. This category aims to capture all topics related to material science, conductivity, and various related engineered materials and concepts such as superconductivity.

Experimentation with materials has played an extremely important role in the development of electronics. Concepts like ferroelectricity, discovered in 1920, and devices like the silicon transistor, developed in 1954, revolutionized the electronics industry; transistors in particular greatly aided in the miniaturization of electronic devices.

IEEE's involvement in these topics spans several technical societies and councils. The IEEE Ultrasonics, Ferroelectrics, and Frequency Control Society , IEEE Dielectrics and Electrical Insulation Society History, IEEE Council on SuperConductivity, and IEEE Nanotechnology Council represent IEEE's interests in these areas.
