A planar pressure transducer is disclosed which is useful for interposing between living tissue and a medical device that applies pressure to the tissue in order to estimate the pressure applied to a selected area of the tissue. The planar pressure transducer comprises a pair of opposed plates between which the proximal ends of optical fibers and a deformable polymer structure are disposed. When the plates are subjected to a pressure acting normally to the plane of the plates an optical signal is obtained via the distal ends of the fibers and related to the pressure acting on the plates.
L'invention concerne un transducteur de pression plan utile s'interposant entre un tissu vivant et un dispositif médical appliquant une pression au tissu afin d'estimer la pression appliquée sur une zone sélectionnée du tissu. Le transducteur de pression plan comprend une paire de plaques opposées entre lesquelles les extrémités proximales de fibres optiques et une structure polymère déformable sont disposées. Lorsque les plaques sont soumises à une pression agissant perpendiculairement au plan des plaques, un signal optique est obtenu par les extrémités distales des fibres et est rapporté à la pression agissant sur les plaques.
