Methods for forming instrumented cutting elements of an earth-boring drilling tool

A method of forming an earth-boring tool, the method comprising:

• forming at least one instrumented cutting element by:
• performing a first high temperature, high pressure (HTHP) sintering process to form a free-standing sintered diamond table having at least one chamber at least substantially entirely enclosed by the free-standing sintered diamond table;
• providing a doped diamond material within the at least one chamber after formation of the free-standing sintered diamond table to form at least one sensing element;
• performing a second HTHP sintering process on the doped diamond material and the sintered diamond table;
• and
• attaching a substrate to the free-standing sintered diamond table with the doped diamond material within the at least one chamber to form the at least one instrumented cutting element such that the doped diamond material is at least substantially entirely embedded within the sintered diamond table on the substrate;
• and
• attaching at least one instrumented cutting element to a body of an earth-boring tool.
