An electrical device including a structure having a plurality of dielectric layers, the structure further having a plurality of vertical electrical connections extending from a top layer of the dielectric layers to a bottom layer of the dielectric layers, a first vertical electrical connection of the plurality of vertical electrical connections including a first capacitive structure that extends in a plane perpendicular to a vertical dimension of the vertical electrical connection, wherein the first capacitive structure is disposed on a first dielectric layer of the plurality of dielectric layers, wherein the first dielectric layer is below the top layer, and a second vertical electrical connection of the plurality of vertical electrical connections including a second capacitive structure extending in the plane and disposed on the first dielectric layer.

Circuits and methods providing mutual capacitance in vertical electrical connections

Methods, systems, and computer readable media for wireless crack detection and monitoring are disclosed. According to one system, a crack detector is affixed to a surface of a material for detecting a crack in the material. In response to detecting a crack, a crack indicator is generated, indicating the existence of the crack. A mote wirelessly communicates the crack indicator to an external device. The mote may also store multiple crack indicators in local memory before being downloaded to the external device. In other embodiments, the mote may time-stamp the crack indicator for indicating a time when the crack was detected. Additionally, the mote may associate other information with the crack indicator such as temperature and acceleration information.
