Claim:
1. A method of forming an instrumented cutting element, the method comprising: forming a free-standing sintered diamond table by performing a first high temperature, high pressure (HTHP) sintering process, the free-standing sintered diamond table having at least one chamber extending from a surface thereof only partially into the free-standing sintered diamond table; providing an electrically conductive doped diamond material within the at least one chamber after formation of the free-standing sintered diamond table and performing a second HTHP sintering process; and attaching a substrate to the free-standing sintered diamond table such that the electrically conductive doped diamond material in the at least one chamber is electrically coupled with a conductive material at an interface of the free-standing sintered diamond table and the substrate.
