ABSTRACT
Resistive, capacitive, inductive, and magnetic (RCIM) sensors are the most widely used sensors, comprising more than 70% of the sensor market today. Their easily understood principles, robust features, simple electronic circuits, low cost, and mature design and manufacturing techniques have made them the first choice in many sensor designs and applications. RCIM sensors can measure pressure, humidity, acceleration, flow rate, radiation, electrical current, electric and magnetic fields, or chemical and biological substances, and are used in a variety of applications, including homeland security, environmental protection, home automation, health care, aviation, as well as food, chemical, and medical industries. This chapter discusses the main characteristics and terminologies of RCIM sensors.
