FIELD: physics.
SUBSTANCE: bearing element has a measuring section having a cavity and at least one geometric irregularity. Stress concentration is formed on the bearing element when pressure is applied to the measuring section near the geometric irregularity. In particular, the geometric irregularity is attached to the optical sensor. The cavity can be filled with liquid or gel. An optical temperature sensor can also be placed near the optical pressure sensor.
EFFECT: high accuracy of measuring pressure and temperature.
