Abstract
Abstract A smart structure or an electronic package is formed by thermal spraying utilizing a plurality of masks positioned and removed over a work surface in accordance with a predetermined sequence. The masks correspond to cross sections normal to a centerline through the structure. Masks are placed above a work surface and sprayed with either at least one primary material to form at least one electronic component and a complementary material. In this manner, layers of material form a block of deposition material and complementary material. Then, the complementary material which serves as a support structure during forming may be removed.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
90 words
An electronic/mechanical structure comprised of layers which layers were formed by spray deposition of at least one primary material and complementary material adjacent said at least one primary material, at least one primary material forming a casing and forming at least one of an electrical conductor and a heat conductor, the electronic/mechanical structure also containing embedded therein at least one of a strain gauge, a capacitive switch and a thermocouple, and a structure which produces an electrical signal when activated by one of a mechanical force and a temperature change.
Claim 2
Dependent Claim
90 words
An electronic/mechanical structure comprised of layers which layers were formed by spray deposition of at least one primary material and complementary material adjacent said at least one primary material, at least one primary material forming a casing and forming at least one of an electrical conductor and a heat conductor, the electronic/mechanical structure also containing embedded therein at least one of a strain gauge, a capacitive switch and a thermocouple, and a structure which produces an electrical signal when activated by one of a mechanical force and a temperature change.
Claim 3
Dependent Claim
