Ultra Low Power Electronics for Autonomous Micro-Sensor Applications

Kairos Microsystems proposes a rugged ultra-low power postage stamp sized wireless micro-sensor node capable of 20m node to node and 1km node to base station communication with an operating life greater than of one year. The small physical structure (20x15x4 mm) is visually non-obvious and the spread spectrum signal is difficult to detect. It may be used as a point sensor or as an array of sensors that report observations to a base station (which may be a UAV), or as a wireless link that replaces wiring. The proposed design incorporates a novel low power receiver that has low suseptibility to interference and wide tolerance for frequency offsets. With a volume price potential of about $2, it can be deployed as a disposable item and used to monitor large areas affordably. BENEFIT: Kairos micro-sensors are suitable for covert military uses, on-soldier medical monitoring, equipment monitoring, perimeter monitoring, and urban warfare building clearance monitoring. Alternate packaging of the micro-sensor will allow dispensing from a UAV into hostile territories.
