Apparatus for electrostatically depositing and retaining materials upon a substrate

Apparatus for electrostatically retaining a deposition material upon a substrate, said apparatus comprising:

• a dielectric layer defining a plurality of first openings, the dielectric layer having a first and second surface;
• a conductive plate, disposed on the first surface of said dielectric layer, defining a plurality of second openings that are coaxially aligned with said first openings;
• a plurality of collection traces, disposed on the second surface of said dielectric layer proximate and extending into said first openings, the collection traces having a first charge polarity;
• and
• a deposition material, having a second charge polarity that is opposite the first charge polarity, where each of said collection traces electrostatically attracts and retains said deposition material.

Apparatus for electrostatically retaining a medicament powder upon a substrate, said apparatus comprising:

• a dielectric layer having a first and second surface;
• a conductive plate disposed on the first surface of the dielectric layer;
• a collection trace, disposed on the second surface of the dielectric layer, where the conductive plate and the collection trace have a parallel spaced-apart relation and the collection trace is disposed on the second surface of the dielectric layer, the collection trace having a first charge polarity that is retained in the absence of a voltage source;
• and
• a medicament powder, having a second charge polarity that is opposite the first charge polarity, wherein the collection trace electrostatically attracts and retains the medicament powder.

An apparatus for electrostatically retaining a deposition material upon a substrate, said apparatus comprising:

• a dielectric layer defining at least one first opening, the dielectric layer having a first and second surface;
• a conductive plate, disposed on the first surface of said dielectric layer, defining at least one opening that is coaxially aligned with said at least one first opening;
• at least one collection trace, disposed on the second surface of said dielectric layer proximate and extending into said at least one first opening;
• and
• a charging plate, for charging each of the collection traces to a first polarity, comprising at least one protuberance extending from a surface of said charging plate, each being formed to fit into a first opening to contact one of said collection traces without contacting said conductive plate, wherein the charging plate is movable between a position where the at least one protuberance contacts a collection trace and a position where the at least one protuberance does not contact a collection trace.
