Abstract:

An impact sensor system includes at least one impact sensor including at least a first conductive layer, at least a second conductive layer, and at least one insulating layer between the first conductive layer and the second conductive layer. The insulating layer maintains the first conductive layer and the second conductive layer in spaced, non-contacting relation. The first conducting layer and the insulating layer are deformable upon an impact to the first conducting layer such that separation between the first conducting layer and the second conducting layer decreases upon an impact of a predefined nature. The impact sensor system also includes circuitry in connection with the impact sensor to measure a change in at least one electrical property of the impact sensor resulting from the decrease in the separation between the first conducting layer and the second conducting layer. A body armor system to be worn by a person includes at least one section of body armor and at least one impact sensor associated with at least a section of the body armor.
