Description
Summary:	Sensors with coupled inductive coils are used in many applications: for metal detection, for linear and angular displacements measurements, for magnetometry, etc. One of the promising ways to increase technical characteristics of these sensors, such as sensitivity, is the use of a chaotic oscillator to excite the transmitting coil and constructing the path from the receiving coil back to the oscillator. The paper proposes several topologies of sensor circuits with coupled inductances, a technique for including inductive coils in chaotic circuits with their minimal modification, and discusses methods for detecting the measurement signal. As a result, we designed a proximity sensor and shown its high performance in a numerical experiment.
