Claim 0:
1. A downhole tool comprising:
a collar; and
one or more sensors secured within the collar for measuring one or more operational characteristics of the downhole tool including condition of the downhole tool during operation of the downhole tool, the one or more sensors including a first sensor including:
a first substrate;
a plurality of strain gauges integrated into the first substrate and configured to measure axial strains and torsional strains on the collar that are transferred to the first substrate for measuring the one or more operational characteristics including the condition of the downhole tool;
a printed circuit board (PCB) integrated into the first 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 one or more sensors, wherein the predetermined calibration parameter is stored in the electronics on the PCB; and
a temperature sensor included 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.
