摘要
A metallic enclosure completely encapsulates an embedded electronic system, which may include sensors, wireless communications devices and other circuits. The enclosure is fabricated in layers of material using a solid-state additive consolidation or lamination process forming a true metallurgical bond between the layers during fabrication without melting the material in bulk. A plurality of enclosures may be provided, each encapsulating an electronic circuit including a wireless transmitter or receiver, with the electronic circuits within the enclosures forming a communications network. As such, a sensor may be used to detect an external characteristic, and a wireless transmitter may be activated to communicate information about the characteristic to a remote receiver. The enclosure may use one or more layers of dissimilar material to form an embedded active or passive electrical component such as an antenna, waveguide, or other device that cooperates with the circuitry.
