TEMPERATURE COMPENSATION FOR STRAIN SENSOR - A simplified explanation of the abstract
This abstract first appeared for US patent application 17747898 titled 'TEMPERATURE COMPENSATION FOR STRAIN SENSOR
Simplified Explanation
The abstract describes a strain sensor that is equipped with a temperature compensation circuit to improve its accuracy. When powered, the temperature compensation circuit applies a voltage to the strain sensor that has a compensating temperature dependency. This compensates for the temperature dependency of the strain sensor itself, resulting in a more stable scale factor between the endured strain and the signal representing the strain.
- The strain sensor has an associated temperature compensation circuit.
- The temperature compensation circuit applies a compensating voltage to the strain sensor.
- The compensating voltage has a temperature dependency that is opposite to the temperature dependency of the strain sensor.
- This temperature compensation improves the accuracy of the strain sensor by providing a more stable scale factor between the endured strain and the signal representing the strain.
Potential Applications
- Industrial monitoring and control systems
- Structural health monitoring in buildings and bridges
- Medical devices for monitoring body movements and forces
- Robotics and automation systems for precise force sensing
Problems Solved
- Inaccurate strain measurements due to temperature variations
- Unstable scale factor between the endured strain and the signal representing the strain
Benefits
- Improved accuracy of strain measurements
- More reliable and consistent scale factor
- Enhanced performance in various applications
Original Abstract Submitted
A strain sensor that has an associated temperature compensation circuit. The strain sensor is temperature-compensated as it has a temperature compensation circuit that, when powered, applies an applied voltage across the applied voltage terminals of the strain sensor that has a compensating temperature dependency. That is, the applied voltage has a temperature dependency of one polarity that is opposite a temperature dependency of the strain sensor. Because of this temperature compensation, the signal representing strain has a more stable scale factor between the endured strain and the signal representing the strain. Thus, the accuracy of the strain sensor is improved.
