METHODS FOR FORMING INSTRUMENTED CUTTING ELEMENTS OF AN EARTH-BORING DRILLING TOOL
First Claim
1. A method of forming an instrumented cutting element, the method comprising:
- forming a free standing sintered diamond table having at least one chamber in the free standing sintered diamond table;
providing an electrically conductive 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 including the doped diamond material disposed within the sintered diamond table on the substrate.

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.
