<p>The sensor (6) has a flexible membrane (11) co-operating with a transmission device (10) that provides, from deformation of the membrane, a value representative of pressure. The membrane is made of amorphous material to optimize dimensions of the sensor. The material has Young's modulus greater than 50 gigapascal, where ratio between elastic limit and the Young's modulus is greater than 0.01. The material comprises a metallic element such as precious metal alloys or precious metallic element e.g. gold, platinum, palladium, rhenium, rhodium, silver, iridium and osmium. An independent claim is also included for a watch comprising a pressure sensor and a conversion unit for converting a value representative of pressure into a depth value.</p> |
