Abstract:
1. A thermocompensated resonator comprising: a body that is deformed in use, the core of the body being formed by a first material, at least one part of the body including at least one coating made of a shape-memory metallic alloy, a thermoelastic coefficient of the shape-memory metallic alloy having an opposite sign to a thermoelastic coefficient of the first material so as to allow said resonator to have a frequency variation as a function of temperature which is substantially zero at least to the first order, wherein the thermoelastic coefficient of the shape-memory metallic alloy represents variations in Young's modulus of the shape-memory metallic alloy as a function of temperature and the thermoelastic coefficient of the first material represents variations in Young's modulus of the first material as a function of temperature.
