Abstract
In at least some embodiments, a tool may comprise a tool body and one or more tool components. The tool may further comprise tool electronics located within the tool body, wherein the tool electronics are operable to sense and store tool component characteristics and environmental characteristics. At least some of the tool electronics are operable, at least for one week, when exposed to temperatures of at least 200 Celsius. The tool electronics may be integrated circuits formed on a silicon carbide substrate or a silicon on sapphire substrate. One illustrative embodiment of the tool is a drill bit for employment in a high temperature drill well.
