METHODS FOR FORMING INSTRUMENTED CUTTING ELEMENTS OF AN EARTH-BORING DRILLING TOOL
First Claim
1. A method of forming an instrumented cutting element for an earth-boring drilling tool, the method comprising:
- forming a sintered diamond table having at least one object embedded therein;
removing at least a portion of the sintered diamond table to access the at least one object embedded therein;
removing the at least one object embedded within the sintered diamond table to form at least one chamber within the sintered diamond table; and
providing an electrically conductive doped diamond material within the at least one chamber to form at least one sensing element within the sintered diamond table.

Abstract
A method of forming an instrumented cutting element comprises forming a free-standing sintered diamond table having at least one chamber in the free-standing sintered diamond table, providing a doped diamond material within the at least one chamber, and attaching a substrate to the free-standing sintered diamond table to form an instrumented cutting element. The instrumented cutting element includes the doped diamond material disposed within the sintered diamond table on the substrate. A method of forming an earth-boring tool comprises attaching at least one instrumented cutting element to a body of an earth-boring tool. The at least one instrumented cutting element has a diamond table bonded to a substrate. The diamond table has at least one sensing element disposed at least partially within the diamond table. The at least one sensing element comprises a doped diamond material.
