  • Method for making an array of micro-needles
    Patent number: 9561355
    Abstract: There is described a method for making an array of micro-needles, comprising the steps of: depositing a plurality of drops of a liquid substance comprising a polymer on a surface of a starting substrate; positioning a pyroelectric substrate at a certain distance from the starting substrate in such a way that the drops deposited are positioned between said surface of the starting substrate and a surface of the pyroelectric substrate; varying the temperature of the pyroelectric substrate or a part thereof to induce on said surface of the pyroelectric substrate a charge density such that starting from the drops deposited, under the effect of an electrodynamic force, respective cones are formed having a tip facing towards the pyroelectric substrate; determining a consolidation of the cones, to form said micro-needles, preventing the tip of said cones from contacting said surfaces of the pyroelectric substrate.
