and even 175°C changed this paradigm and enabled the creation of MEMS-based directional modules able to op- erate at extreme temperatures for long period of time.

However, most of the high-temperature MEMS accel- erometers available on the market tend to demonstrate a highly degraded accuracy under high vibrations and shocks, limiting their usage to static measurement with successive start-and-stop sequences of the drilling mo- tor. In addition, these devices often rely on analog-centric electronics architectures, requiring electronics engineers to handle analog-to-digital conversion at system-level with additional discrete components.
