Claim 13:
14. A sensor of a downhole tool comprising:
a substrate configured for positioning within a collar of the downhole tool;
a plurality of strain gauges integrated into the substrate and configured to measure axial strains and torsional strains on the collar that are transferred to the substrate for measuring one or more operational characteristics including a condition of the downhole tool;
a printed circuit board (PCB) integrated into the substrate, wherein the PCB includes electronics electrically coupled to the plurality of strain gauges and configured to concurrently calibrate the electronics and the plurality of strain gauges based on a predetermined calibration parameter and control operation of the sensor of the downhole tool, wherein the predetermined calibration parameter is stored in the electronics on the PCB; and
a temperature sensor Ided in the PCB in proximity to the plurality of strain gauges and configured to measure temperature at the plurality of strain gauges, wherein the plurality of strain gauges is configured and controlled based at least in part on the temperature at the plurality of strain gauges.
