Dimension (mm)
Three-dimensional force sensors play an important role in multiple fields. In industrial robotics, 3D force sensors installed on the robot’s end effector sense the force information when the robot contacts the workpiece, enabling force control in precision assembly, grinding, and polishing operations. This prevents damage to the workpiece due to excessive force or compromised processing quality due to insufficient force.
In aerospace, 3D force sensors are used for force measurement in aircraft engine testing and spacecraft docking mechanisms, providing data support for equipment performance evaluation and safe operation. In automotive manufacturing, they are used for strength testing and collision testing of automotive components, measuring the mechanical response of components under different load conditions.
In biomedicine, 3D force sensors are used in minimally invasive surgical robots to measure the interaction between surgical instruments and human tissue, enabling doctors to perform more precise operations and minimize trauma to patients. In sports research, they can be used to analyze the force exerted by athletes’ movements, providing a scientific basis for training.
