Des chercheurs israéliens développent un minuscule capteur de tension artérielle qui pourrait remplacer les brassards traditionnels
Le capteur utilise des impulsions de lumière pour générer des ondes ultrasonores à l'intérieur d'une artère
Évaluation
A new light-based sensor small enough to fit inside an artery could make the familiar inflatable cuff obsolete. The technology generates ultrasound waves from light pulses to measure pressure directly from within the vessel. If trials succeed, it would mean continuous monitoring for patients who currently get only snapshots. The key question is how the device fares in long term safety and accuracy testing.
