Abrégé

An oscillator spring made of a spring material consisting of any of carbon, ceramic, polymer, polymer precursor, composite and any combination of these materials, and a barrier material for altering the number of bonding sites which are available at the surface of the spring material, wherein the barrier material consists of one or more hydrophobic silicone compounds or one or more hydrophobic silane compounds. The barrier material can provide a full or partial barrier to the adsorption of water vapour in the ambient atmosphere. The barrier may thus enable the elasticity of the spring to be regulated.

Abrégé

An oscillator spring material comprising a mixture of a host material with an additive in proportions which permit the thermal evolution of the material's elastic modulus to be tuned, e.g. to correct or compensate for other thermal changes in an oscillator system. The additive comprises a crystalline material having an abnormal thermal evolution of elastic modulus. The host material has a normal thermal evolution of elastic modulus. The additive is mixed with the host material before the host material undergoes a phase transformation into its final form. The additive has a phase transformation temperature higher than the host material, so that additive remains in the same state while the host material phase transformation takes place.
