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 based response techniques have been developed for AT systems. These systems require a means to constantly power the AT system for long periods of time. Current energy storage technologies such as batteries and capacitors are insufficient for 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 less reliable response of the AT system. To solve this challenging problem, Midé proposes to develop safe and reliable smart materials based AT sensors. These sensors will require no power and will scavenge energy from the intrusion event to either “turn on” the powered AT system or directly destroy the CPI. Additionally, the output of the smart material sensors will be directly correlated to the intensity of the tamper event. The more energy (thermal, shock, vibration) 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 input energy.
