SATT (Smart Anti-Tamper Technologies)

The protection of CPI from unwanted transfer is necessary to ensure a tactical advantage over our adversaries. Various powered sensor response techniques have been developed for AT systems. These systems require a means to be constantly powered for long periods of time. A downed or stored weapon system may need protection for many years removed from a primary power source. Energy storage technologies such as batteries and capacitors are insufficient for these AT systems due to their limited capacity. A tradeoff between sensor measurement frequency and battery capacity requires that either less sensors are used or that the frequency at which the sensors are measured is reduced. This leads to a less effective AT system. To solve this challenging problem, Midé is developing reliable smart materials based AT sensors. These sensors require no power and scavenge mechanical energy from the intrusion event to “turn on” the powered AT system. Additionally, the output of the smart material sensors is directly correlated to the intensity of the tamper event. The more energy that is provided to the smart sensor, the more energy the sensor will deliver. This output will allow the AT system to tailor its response to the tamper event.
