elements and the signals are conveyed to the data collection module not shown such data transmission may include wired or wireless communication one or more embodiments may be used to measure the temperature of a cutter 1 attached to a drill bit in operation in an economical manner such measurements may provide improved bit performance monitoring and control as well as providing an improved understanding of cutter behaviour in use although the foregoing description contains many specifics these are not to be construed as limiting the scope of the present disclosure but merely as providing examples of embodiments similarly other embodiments of the disclosure may be devised which do not depart from the scope of the present disclosure various modifications may be made to the present disclosure for example whilst various embodiments have been described in which the body of pcd material comprising the temperature sensor is designed for use as a cutter in the oil gas drilling industry temperature information is often required in other environments which could lead to a rapid chemical or erosive wear of a sensing device and therefore the body of pcd material could be used as a temperature sensing device for use in harsh chemical and erosive environments rather than forming part of a cutter furthermore whereas some embodiments are directed to the use of a pdc cutter as the temperature sensor where the sensing device forms an active part of the application that is cutting rock with the device itself other embodiments pertain more to a pcd table with appropriately fitted electrodes used as a passive device fitted somewhere inside a.
