A syringe, particularly for medical and veterinary use, of the multi-chamber, single-use and preloaded type, comprising a containment cylinder forming a compartment for containment and mixing for substances to be injected, which can be mated with a tubular element. The crankshaft is structured to move the tooling assemblies associated with less than the total number of lanes. The second silicon body has a conductivity type opposite the majority charge carrier conductivity type. The protective nitride film is positioned, as seen from above, inner than a portion of the isolation film exposed on the main surface of the silicon substrate. The elongated electrode portion faces a flat electrode portion having a flat shape, with one of the dielectric layers interposed therebetween.
