ShapeAccelArray (SAA) is a sensor that can be placed in a borehole or embedded within a structure to monitor deformation. It consists of a continuum of segments containing triaxial, micro electro mechanical system (MEMS) accelerometers (Danisch et al, 2008). Each segment has a known length. By sensing the gravity field at each segment, the bend angles between each segment can be calculated. Using the calculated bend angles and known segment lengths, the shape of an SAA can be determined. SAA can be used to determine 3D shape when installed vertically and 2D shape when installed horizontally. 3D shape can be determined when SAA is installed up to 60 degrees from zenith.
