A sensor based on a paramagnetic substance (titanium nickelide) is developed. An element made of this material is capable of oscillating under constant mechanical loading with a cyclic temperature change relative to a certain critical point at which a phase transition of a substance from one modification to another takes place. Near this critical point, the system is essentially nonlinear and potentially capable of reacting to the effects of external factors that determine environmental conditions.
