Stress represents the force per unit area within materials that arises from externally applied forces, uneven heating, or permanent deformation and that permits an accurate description and prediction of elastic, plastic, and fluid behaviour. SI unit of stress is Pascal (Pa), but can be described through other units, such as bar or atmosphere (atm).
The RVmagnetics Microwire Sensor is extremely sensitive to physical force, thus can provide real-time sensing of stress.
