Research team develops novel biomimetic speaking valve technology
The challenge: if conventional speaking valves are used improperly, dangerous overpressure can occur, which can cause serious complications and even death. In a collaboration at the University of Freiburg, researchers developed a speaking valve with an integrated pressure release valve and an acoustic warning signal, inspired by the trapping mechanism of the carnivorous bladderwort plant Utricularia vulgaris.
