1. A rotary drill bit configured to be conveyed in a borehole and drill an earth formation, the rotary drill bit comprising:
- at least one polycrystalline diamond compact (PDC) cutter including;
(i) at least one cutting element, and(ii) at least one transducer configured to provide a signal indicative of at least one of;
(I) an operating condition of the drill bit, and (II) a property of a fluid in the borehole, and (III) a property of the surrounding formation.

Abstract
A Polycrystalline Diamond Compact (PDC) cutter for a rotary drill bit is provided with an integrated sensor and circuitry for making measurements of a property of a fluid in the borehole and/or an operating condition of the drill bit. A method of manufacture of the PDC cutter and the rotary drill bit is discussed.
