4DShape

4DShape is an integrated monitoring system that uses a flexible chain of 3D inclinometers to track relative movement along vertical, horizontal, or converging profiles in soil and structural environments. Many users may also search for this type of system under the name ShapeArray (SAA).

Built on advanced MEMS (Micro‑Electro‑Mechanical Sensor) technology, 4DShape offers a modern, efficient, and highly optimized approach to deformation monitoring across a wide range of applications, including Slope Stability Monitoring.

4DShape: Chaining 3D Inclinometers

The 4DShape system is composed of rigid unit lengths (called segments) connected by joints that allow rotation while preventing torsion. Each segment contains three MEMS inclination sensors, a microprocessor, and a digital temperature sensor. Segment lengths range from 7.9 inches to 3.28 feet, enabling significantly higher accuracy than conventional inclinometer systems.

Depending on the project, a 4DShape installation may span a few feet up to approximately 492 feet, and it can be deployed in vertical, horizontal, or converging configurations. Its durability, compact form factor, and high‑resolution measurement capabilities make it ideal for drilling operations, structural wall monitoring, and tunnel or pipeline inspections.

4DShape Applications

Thanks to its flexible installation options, 4DShape supports a wide variety of monitoring needs. Common applications include:

Automated borehole deformation measurements
Tunnel and gallery convergence monitoring
Settlement tracking along horizontal alignments (embankments, rail corridors, etc.)
Deformation monitoring of vertical structures such as walls and columns
Slope stability monitoring for landslides and geotechnical risk areas

Results are typically visualized through the Geoscope online platform, providing clear interpretation and time‑based analysis.
