The working principle of a 3D force sensor

Release Time:

2025-11-01

The 3D force sensor is based on the principle of resistance strain gauges, utilizing a resistive strain-type sensing element—also known as a strain-gauge 3D force sensor. It consists of an elastic component, resistance strain gauges, and a Wheatstone bridge circuit.

A strain gauge is the sensitive element used to fabricate sensors that measure various physical quantities. When attached to the elastic component of a three-dimensional force sensor, it becomes the strain-resistance conversion element—this is the core component of a weighing sensor. The force exerted by the object being weighed deforms the elastic element, causing strain. The strain gauge bonded to the elastic component then converts this strain, which is proportional to the object's weight, into a corresponding change in electrical resistance. Finally, a Wheatstone bridge circuit transforms this resistance change into a voltage output, which is displayed on an instrument, thereby completing the measurement task.

How does the multi-dimensional force sensor enhance calibration efficiency?

Typically, a Design Of Experiment (DOE) is employed to generate a scientifically sound load table, while Regression Analysis (RA) is used to establish the functional relationships between dependent and independent variables. Ultimately, the calibration matrix obtained depends heavily on both the load table and the regression analysis method applied. Established force measurement laboratories usually have their own standardized procedures for acquiring and processing this data—though sometimes the individuals directly involved in calibration work may not even be fully aware of the underlying data calculation processes driving the calibration workflow.

Three-Dimensional Force Sensor Calibration Data Processing Method

To simultaneously measure multi-component forces and torques, a multidimensional force sensor is required, which inevitably demands calibration before use—otherwise, the conversion from electrical signals to physical force values cannot be accurately achieved.

Calibration Method for Six-Dimensional Force Sensors

Calibration of multi-component force sensors aims to establish the relationship between the signal and the applied force. The calibration process can be expressed as a quadratic polynomial. Interestingly, this representation differs slightly from what’s typically found in domestic textbooks—where we usually place the force F on the left side of the equation. From the perspective of the calibration procedure, however, this arrangement seems more logical, since it reflects applying a specific force and subsequently measuring the corresponding signal.
