Abstract
A device for providing electrical energy in a submunition of a projectile upon an expulsion acceleration of the submunition from the projectile, the device including: at least one elastic element and a mass connected to the at least one elastic element such that a firing acceleration of the projectile deforms to store mechanical energy in the elastic element; and a mechanism for locking the elastic element in the deformed position and unlocking the elastic element due to the expulsion acceleration to vibrate the at least one elastic element and mass and apply a cyclic force to at least one piezoelectric element to convert the stored mechanical energy to electrical energy.
