Advances in technologies are providing opportunities to increase situational awareness in military operations. One application of these technologies is small disposable sensor systems that have the potential to enhance the war-fighter's lethality and survivability. Considering that the sensors must be disposable, cost constraints increase the complexity of solving the technical and operational challenges. This paper will address two areas of consideration when designing disposable sensor systems: technical and operational. Technical design considerations: Sensor communication networks are a hot area of development, with a multitude of standards and protocols to choose from. Miniaturization is providing a multitude of sensor modalities that can be considered for a disposable sensor. Decisions must be made between factors such as cost, size, and power requirements. Power management through hardware and software, coupled with more efficient batteries, is giving extended life to sensor systems. Environmental issues must be addressed in a disposable system. Operational design considerations: For systems monitored and managed directly by soldiers, one of the most important elements is the user interface, and its affect on overall system ease-of-use. System usefulness is also affected by the capability to autonomously monitor the area where sensors are deployed without a soldier present. The packaging of sensors will be affected by the current state of technology integrated into the sensors, as well as requirements for emplacement. These emplacement requirements and constraints will impact the operational effectiveness of the overall system.
