There is described a method for making an array of micro-needles, comprising the steps of:

Method for making an array of micro-needles

Production and the distribution of pico and nano-drops, which are extracted by the effect of a strong electric field generated by pyroelectric effect, in particular, but not exclusively, from a sessile drop (a drop placed on a surface assumes a form termed 'sessile') or by a liquid film, and distributed on a dielectric substrate. The electric field is advantageously generated applying a heat source on the dielectric substrate or utilizing a laser source emitting in the infrared region. In this new approach, it is not necessary to use fixed electrodes, circuits, high tension generators or to design intentionally, and therefore to realize, pico- and nano-nozzles.

Device for controlled distribution of micro- or nano-volumes of a liquid based on the piezoelectric effect in functionalized materials, without using external electric sources
