Title (EN) MICROFLUIDICS WITHOUT ELECTRICALLY OF MECHANICALLY OPERATED PUMPS
(FR) LOGIQUE A MICROFLUIDES SANS POMPE
Abstract:
(EN) A microfluidic device which operates without the need for an external power source. The device includes a body structure, at least one microscale channel within the structure, a port for introducing fluid into the channel, and a power source internal to the structure for propelling the fluid through the channel. Various structures are described which embody the invention.
(FR) L'invention concerne un dispositif à microfluides pouvant fonctionner sans source d'énergie externe. Le dispositif comprend un corps, au moins un microcanal situé dans la structure, un port permettant l'introduction de fluide dans le canal, et une source d'énergie interne à la structure, destinée à propulser le fluide dans le canal. Diverses structures constituant des configurations de l'invention sont décrites.
