Abstract
The drilling system withstands downhole conditions at the bottom of the borehole and drilling conditions due to the constant movement and vibration. The drilling system includes a drill bit and a sensor system with a system housing, a primary power supply and interior sensor. The primary power supply includes piezoelectric panels for converting radial vibration into energy. The interior sensor is locally powered by the primary power supply at the remote downhole location at the bottom of the borehole. The interior sensor collects data related to a downhole condition and is in communication with the primary power supply to generate confirmed data based on the amount of energy generated by the primary power supply. The confirmed data is more accurate and reliable than the data collected by the interior sensor and can be used to guide the path of the drill bit through the rock formation in drilling operations.
