Pressure sensor for watch, has flexible membrane cooperating with transmission device to provide value representative of pressure from deformation of flexible membrane, where membrane is completely made out of amorphous material

摘要

The sensor (6) has a flexible membrane (11) cooperating with a transmission device (10), so as to provide a value representative of the pressure from the deformation of the flexible membrane. The membrane is completely made out of amorphous material, where the Young's modulus of the material is greater than 50 gigapascals. The amorphous material includes a noble metal or an alloy of the noble metal selected from one of gold, platinum, palladium, rhenium, ruthenium, rhodium, silver, iridium or osmium. An independent claim is also included for a watch.
