The fluid distribution device includes a first cavity at a first pressure and a second cavity at a second pressure lower than the first pressure. A partition separates the first cavity from the second cavity and a restricting valve is arranged between the first and second cavities. The partition includes a thermoelectric module having a hot side in thermal contact with the first cavity and a cold side in thermal contact with the second cavity.

A microfluidic component comprises at least one closed microchannel filled with nanostructures. The microchannel is produced by previously forming an opening delineating a bottom wall and two opposite side walls of the microchannel in a surface of a substrate. The nanostructures filling said microchannel are formed by in situ growth to constitute a layer of metallic catalyst deposited on said side walls and on said wall bottom. The microchannel is closed, before the nanostructures are formed, by sealing a protective cover onto said surface of the substrate. Sealing is obtained by formation of an eutectic compound between a material of the cover and the metal of the catalyst used for in situ growth of the nanostructures and deposited on the surface of the substrate designed to come into contact with the cover.

A new anode configuration () is proposed for a lithium microbattery (). The anode () preferably consists of nanotubes or of nanowires () such that the empty space () left between the different components () provides compensation for the inherent swelling upon discharging the microbattery (). With the absence of stresses on the electrolyte (), the lifetime of the battery () may be increased.
