Propellants, Explosives, Pyrotechnics, Volume 50, Issue 1, January 2025.Abstract The ability to transmit electrical signals through high explosive charges without using dense metal conductors could enable continuous monitoring of explosive charges with internally embedded sensors. With the sensor materials themselves being energetic, the impact on the intended detonation performance of the charge can be minimized. Embedded
