Abstract: There is an increase in the number of autonomous battery driven devices in the world today and also a growing need for rapid information of unwanted incidents. By combining the GMS- and GPS-technology with the invention and any sensor with the ability to generate a voltage due to external influences, one has reached an activation device perfect for alarm devices that can lay dormant for years with no mentionable power consumption until the day a certain incident occurs. This trait can be used in numerous applications where only the sensor type sets the limits. By using a piezoelectric gyroscope as sensor for instance, a potent tracking device is made, where motion generates a voltage, which in turn will activate the entire device that will instantly start tracking the movement of the device and report this to its owner. This device will be of very small dimensions it can be attached to or hidden somewhere on personal belongings of a certain size; bags, suitcases, bicycles, paintings etc.
