Abstract: The invention relates to a sensor comprising a substrate and an electrode formed on the substrate wherein the electrode comprises a binder and a conductive material containing doped diamond particles. The invention extends to methods of producing the sensor.

Abstract: A microelectrode comprising a diamond layer formed from electrically non-conducting diamond and containing one or more pins or projections of electrically conducting diamond extending at least partially through the layer of non-conducting diamond and presenting areas of electrically conducting diamond.

Abstract: A body of single crystal CVD (chemical vapour deposition) diamond particularly suitable as a wear resistant material for wear applications, such as wire drawing dies, graphical tools or stichels, or fluid jet nozzles. The diamond typically has a low wear rate, exhibits a low birefringence indicative of low strain and possesses an ability to be processed to show a high surface polish.

Abstract: A cutting insert, particularly a razor blade or surgical blade, including a layer of diamond having a cutting edge defined at the intersection to two converging surfaces. The converging surfaces are coated with a layer of diamond-like carbon (DLC).

Abstract: A microelectrode comprising a diamond layer formed from electrically non-conducting diamond and containing one or more pins or projections of electrically conducting diamond extending at least partially through the layer of non-conducting diamond and presenting areas of electrically conducting diamond.

Abstract: A method and system is disclosed for monitoring one or more characteristics associated with a fluid. An insulating layer comprising non-conducting diamond is positioned within a housing and has a surface exposed directly or indirectly to the fluid. A plurality of microelectrodes made of electrically conducting diamond each have a surface exposed directly or indirectly to the fluid. An electrical circuit in electrical communication with each of the microelectrodes is adapted to convert electrical signals from the microelectrodes into at least one signal associated with a characteristic being monitored.
