Abstract

An electronic device includes at least one terminal formed on the electronic device. The electronic device also includes at least one of a semiconductor device, an integrated circuit chip, and a computer. A seamless conductive mesh is formed on at least one surface of the electronic device. The conductive mesh is in electrical contact with the terminal. The terminal facilitates electrical conduction between the conductive mesh and an electrical detection circuit. The electronic device also may include a pattern having traces formed on at least two surfaces where each of the traces includes a continuous loop of conductive material is formed on at least two surfaces. The electronic device also may include a first plurality of conductive loops formed on the electronic device that are continuous and surround the electronic device in a first direction and a second plurality of conductive loops formed on the electronic device that are continuous and surround the electronic device in a second direction.
