Publication number: 20140377091Abstract: A pump devoid of mobile mechanical parts and including a tank with a sleeve for dispensing fluid that remains fully open, but of which an inside capillary is too thin to allow for dispensing of fluid when idle. Recourse is therefore made to a resonator device with a piezoelectric exciter, that produces vibrations, in particular bending, of the sleeve to oblige the fluid to flow through it at a determined flow rate that depends on characteristics of the pump and of excitation. The assembly can be miniaturized and used as an implantable device, for example for treatment of hearing pathologies, to deliver a drug, or, in certain embodiments, also take samples of ambient fluid. A remote energy supply is possible.Type: ApplicationFiled: September 21, 2012Publication date: December 25, 2014Applicant: COMMISSARIAT A L'ENERGIE ATOMIQUE ET AUX ENE ALTInventors: Elisabeth Delevoye, Jean-Pierre Nikolovski

Publication number: 20080213539Abstract: The invention relates to a method of maintaining the optimal properties of a thin film getter (10) in a cavity (8) of a microelectronic device (1), consisting in coating the getter film (10) with a protective film (12) and installing a reaction element (14). According to the invention, an increase in temperature, while the cavity (8) may be placed under vacuum, causes the protective film (12) to react with the reaction element (14), such that the protective material (12) moves towards the reaction element (14) and releases the getter film of getter material (10).Type: ApplicationFiled: March 10, 2006Publication date: September 4, 2008Applicant: Commissariat A L'ENERGIE ATOMIQUEInventors: Jean-Charles Souriau, Elisabeth Delevoye, Francois Baleras, David Henry
