    Abstract: Structural health monitoring systems for building structures created by additive processes can include at least an orientation sensing subsystem, a strain sensing subsystem, and a local processor. Orientation sensors can collect data from a first set of strategic locations and strain gauges can collect data from a second set of strategic locations on a 3D-printed building component. The sensors can be embedded during or after the 3D-printing process. A simulation engine can determine the strategic locations by modeling 3D geometry and material properties and simulating results from the application of various loads to determine the likely structural failure locations of the building component. The local processor can receive sensor data, filter the data, format the data for analysis, store the data, and forward the formatted data to a remotely located processing system for analysis. Additional system components can include an environmental subsystem and tensometers to collect humidity, temperature, and material deformation data.

    Abstract: A pressure sensing mat including a first conductive layer, a second conductive layer, and an insulative layer disposed therebetween. The first conductive layer includes a first plurality of spaced apart conductive paths and a first plurality of non-conductive paths therebetween and defining a plurality of gaps in the first plurality of non-conductive paths having a first repeating pattern of a cross shape. The first plurality of spaced apart conductive paths and the first plurality of non-conductive paths extend in a first direction. The second conductive layer includes a second plurality of spaced apart conductive paths and a second plurality of non-conductive paths therebetween and defining a second plurality of gaps in the second plurality of non-conductive paths having a second repeating pattern. The second plurality of spaced apart conductive paths and the second plurality of non-conductive paths extends in a second direction different than the first direction.

    Abstract: According to one embodiment, an electronic device includes a first substrate, a second substrate opposing the first substrate, a pressure sensitive layer disposed between the first substrate and the second substrate, and an elastic member that covers the first substrate, the second substrate and the pressure sensitive layer. The first and second substrates include a first and second insulating substrates formed into a mesh-like shape. The elastic member includes slits that are formed around a first island-shaped portion of the first insulating substrate and a second island-shaped portion of the second insulating substrate. The slits open when the elastic member is expanded.

    Abstract: An article of apparel and method include a structure configured to enclose a human body part, a pressure sensor array including multiple pressure sensors separately positioned at locations within the structure, wherein each pressure sensor is configured to output a signal indicative of an amount of pressure being exerted on the pressure sensor by an external mechanical force, an electronic display, and a controller. The controller is configured to receive signals from the pressure sensors and, based on a sequence and a timing of the signals as received, determine a command related to a function of a device. The electronic display is configured to display information related to the function.
