REMOTELY ADDRESSABLE PRESSURE AND/OR TEMPERATURE MEASURING DEVICE INSTALLED IN A BIOLOGICAL MEDIUM

摘要

The invention relates to a pressure and/or temperature measuring device that can be remotely addressed and comprises at least: an acoustic wave sensor including at least one resonator coupled to a first antenna member; an addressing system including a second transmission and reception antenna member, characterised in that it includes an expansible tubular structure (42), wherein said structure comprises a biocompatible material (46) with the acoustic wave sensor (36, 38, 40) encapsulated in the biocompatible material, and in that the second antenna member operates at frequencies higher than several tens of Megahertz.
