1. A drilling system, comprising:
a drill bit having a terminal end, a connection end opposite the terminal end, and an interior channel extending from the connection end toward the terminal end; and
a sensor system being mounted in the interior channel and comprising:
a system housing having a distal end, a proximal end opposite the distal end, a center housing axis being co-axial with said interior channel, a center chamber between the distal end and the proximal end, and a power chamber between the center chamber and the proximal end, said center chamber being co-axial with said interior channel;
a primary power supply being mounted in the power chamber and being comprised of:
a plurality of piezoelectric panels radially arranged around the center housing axis within the power chamber so as to convert radial vibration into energy; and
a housing capacitor connected to the plurality of piezoelectric panels; and
an interior sensor being mounted in said center chamber and being connected to the primary power supply so as to collect data related to a downhole condition,
wherein the interior sensor and the primary power supply are in communication so as to generate confirmed data based on the data related to a downhole condition and an amount of energy generated by said primary power supply.
