Electrically patterned polycrystalline diamond compact for sensing applications

A method, comprising:

• providing a polycrystalline diamond compact component;
• treating, via an energy source, the polycrystalline diamond compact component to form one or more graphene surfaces such that the polycrystalline diamond compact component is an electrified polycrystalline diamond compact component, wherein the one or more graphene surfaces generate an electrical signal based on a combination of two or more of an applied pressure, an applied strain, an applied electrochemical potential, or an applied electromagnetic field;
• and
• providing a controller to perform one or more operations comprising:
• receiving and actively monitoring the electrical signal generated by the electrified polycrystalline diamond compact component;
• and
• processing the electrical signal to generate one or more output parameters based on a mechanical, physical, or chemical change of the one or more graphene surfaces,
• wherein the one or more output parameters comprise a thickness of the one or more graphene surfaces, a remaining amount of the one or more graphene surfaces, or a time period indicative of when to discontinue use of the electrified polycrystalline diamond compact component.

A system, comprising:
