Sensors in earth-boring tools, related systems, and related methods

A method of determining a drilling parameter, the method comprising:

• providing an earth-boring tool, comprising:
• a body;
• a recess formed in a wall of the body;
• a sensor-securing system disposed within the recess and comprising:
• a first wedge member disposed within the recess and comprising a shallow valley formed in a lateral side of the first wedge member;
• a second wedge member disposed within the recess and adjacent to the first wedge member, wherein the first wedge member and the second wedge member define a first tapered aperture and a second tapered aperture;
• a first tapered fastener disposed within the first tapered aperture;
• and
• a second tapered fastener disposed within the second tapered aperture, wherein the first and second wedge members are configured to separate when the first and second tapered fasteners are tightened;
• and
• a sensor disposed between the first wedge member and a sidewall of the recess, and wherein the shallow valley of the first wedge member is configured to abut up against the sensor;
• and
• measuring at least one drilling parameter with the sensor.

A method of determining a drilling parameter, the method comprising:

• providing an earth-boring tool, comprising:
• a body;
• a recess formed in a wall of the body;
• a cap portion disposed within the recess, the cap portion comprising at least one sputtered strain gauge formed on an inner surface of the cap portion;
• and
• a sensor disposed within the recess between a base of the recess and the inner surface of the cap portion;
• and
• measuring at least one drilling parameter with the sensor.
