Research Institution
There exists a need for near-real time detection and location of small quantities of waterborne biological agents by the warfighter. Since surface water is the primary water source for field soldiers, there is a critical need to determine the extent of potability. The objective of the proposed work is to design and build a small, low cost, highly selective, immunoassay based optical sensor/communication module that can be taken into the field by soldiers to wirelessly monitor streams and effluents for the detection of biological agents. This (Module) will include signal-conditioning circuitry and a radio frequency (RF) transmitter subsection. The signal conditioning subsection will process the raw signals from the sensor subsection and the RF section will transmit a device ID number together with an alarm indication. A soldier, using a handheld reader developed for the purpose, will be able to determine if modules are within communication range and whether any indicate an alarm condition. Work will concentrate on fabricating and testing: multi-pathogen sensor elements, a short range radio communication section, a long range satellite communication section, and the housing/packaging. Work will culminate with the demonstration in a simulant effluent environment.
