A device which electrically triggers unattended weapon system at command (safety or arm) without a battery is proposed. Applications include remote control of explosives, fusing of mines, or activating missiles. Such a triggering device without battery operates after being stored for a long time, while the conventional method relying on a battery suffers from relatively short and unpredictable shelf life of the battery. The device can be utilized also for identifying a weapon (i.e. Mine) installed in ground or water for removing after the need diminishes. The device contains an electric energy pump which supplies electric energy for 1) storage and 2) operating a piezoelectric switch triggering the weapon. The experimental feasibility study proposed concentrates it efforts in piezoelectric energy pumping technique. The device which consumes no measurable power during the standby condition, yet is capable of accepting a remote command signal to operate, self-generate electricity, activate a load, small and low-cost, will have many military, industrial and commercial applications.
