1. A microfluidic cartridge comprising:
an interior;
an exterior;
a reservoir disposed in the interior of the microfluidic cartridge, the reservoir comprising a fluid composition comprising a perfume mixture;
an electric circuit disposed on the exterior of the microfluidic cartridge, the electric circuit comprising a first end portion having electrical contacts and a second end portion opposing the first end portion;
a microfluidic die disposed on the exterior of the microfluidic cartridge, wherein the microfluidic die is electrically connected with the second end portion of the electric circuit and in fluid communication with the reservoir; and
a silicone pressure-sensitive adhesive joining the electric circuit with the exterior of the microfluidic cartridge, wherein the silicone pressure-sensitive adhesive provides sufficient interfacial adhesion strength to secure the electric circuit with the microfluidic cartridge.
