A method for providing electrical energy to a self-destruct fuze for submunitions in a projectile, the method including: storing mechanical energy in an elastic element attached to a first movable mass at one end of the elastic element upon a firing acceleration of the projectile; engaging a second movable mass with the first movable mass such that movement of the second movable mass upon the acceleration moves the second movable mass which in turn moves the first movable mass; converting the stored mechanical energy to electrical energy upon the acceleration to vibrate the first movable mass and the elastic element to apply a cyclic force to a piezoelectric element attached to another end of the elastic element; and locking the second movable mass in a position where the second movable mass cannot interfere with vibration of the first movable mass upon the second movable mass being subjected to the acceleration.

A method for providing electrical energy in a projectile upon an expulsion acceleration of the projectile. The method including: using a firing acceleration of the projectile to deform at least one elastic element to store mechanical energy in the elastic element; 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 apply a cyclic force to at least one piezoelectric element to convert the stored mechanical energy to electrical energy.
