A strain and crack sensor senses an amount of strain induced in an object. A receiving planar antenna has a first resonant frequency and is configured to receive a querying signal at the first resonant frequency. A transmitting planar antenna has a second resonant frequency that is twice the first resonant frequency. At least one of the receiving planar antenna and the transmitting planar antenna is bonded to the object so that at least one of strain induced in the object or a crack formed in the object causes a shift in at least one of the first resonant frequency or the second resonant frequency. A matching element is in electrical communication with the first planar antenna and the second planar antenna. The matching element is configured to cause the transmitting planar antenna to radiate a response signal in response to the querying signal.

Frequency doubling antenna sensor for wireless strain and crack sensing

An exemplary embodiment of the present invention provides a passive electrical component comprising a substrate, a first electrically conductive layer, a first dielectric layer, and a second electrically conductive layer. The first electrically conductive layer can be additively deposited on the substrate. The first dielectric layer can be additively deposited on the first conducive layer. The first dielectric layer can comprise a cross-linked polymer. The second electrically conductive layer can be additively deposited on the first dielectric layer. The resonant frequency of the passive electrical component can exceed 1 gigahertz.

Additively deposited electronic components and methods for producing the same

An antenna includes a dielectric sheet and a conductive film. The dielectric sheet is folded into a plurality of fold segments and is configured to be compressed into a compressed state and to be expanded into an expanded state. The conductive film is disposed on a portion of the dielectric sheet. The conductive film has a pattern that defines a current path from the bottom of the dielectric sheet to the top of the dielectric sheet. The pattern is configured so that the each of the plurality of fold segments includes a portion of the pattern and so that the portion of the pattern on each fold segment is substantially non-juxtaposed with respect to the portion of the pattern on each adjacent fold segment when the dielectric sheet is fully compressed into the compressed state.
