The second volume of Handbook of Humidity Measurement "Electronic and Electrical Humidity Sensors" is entirely devoted to the consideration of different types of solid-state devices which can be used for humidity measurement. There is given a detailed information, including advantages and disadvantages about the capacitive, resistive, gravimetric, hygrometric, field ionization, microwave, solid-state electrochemical, and thermal conductivity-based humidity sensors, followed by a relevant analysis of the properties of humidity-sensitive materials, used for the development of such devices. Humidity sensors based on thin film and field-effect transistors, heterojunctions, flexible substrates, and integrated humidity sensors are also discussed in this volume. Great attention is also paid to the consideration of conventional devices, which were used for the measurement of humidity for several centuries. It is important to note that many of these methods are widely used so far.
