Abstract: Incontinence management systems, methods, and sensors are provided that alert the caregiver when a patient's brief has been soiled. A resonant circuit includes a polyaniline/carbon black (PANI/CB) composite chemiresistor which undergoes a large impedance change upon exposure to the vapor or ‘smell’ of urine or feces. Due to the impedance change of the PANI/CB resistor, characteristics of the resonant circuit change when the sensor is exposed to urine or feces vapor. The sensor responds to an interrogating signal with a signal based least in part on the sensor's impedance and indicates the condition of the brief as soiled or clean.

Abstract: The invention generally relates to an airborne deployed passive radio frequency identification system and a method to identify an analyte and then to communicate a result of the analyte identification to a receiving station for an analysis and generation of a set of recommended actions. The invention will enhance the situational awareness and preparedness of forward deployed combat troops or security forces by assessing the presence of benign substances or hazardous substances as they advance and enter an area.

Abstract: A system for detecting chemical/biological substances and a detection method. The system comprises a plurality of sensing units or nodes and a radiofrequency link. Each unit has several sensors with different sensing curves. Each sensor is able to transmit information related to the sensed substance on a specific frequency. The sensors preferably comprise AlGaN/GaN high electron mobility transistors.

Abstract: Methods of fabricating nano-gap electrode structures in array configurations, and the structures so produced. The fabrication method involves depositing first and second pluralities of electrodes comprising nanowires using processes such as lithography, deposition of metals, lift-off processes, and chemical etching that can be performed using conventional processing tools applicable to electronic materials processing. The gap spacing in the nano-gap electrode array is defined by the thickness of a sacrificial spacer layer that is deposited between the first and second pluralities of electrodes. The sacrificial spacer layer is removed by etching, thereby leaving a structure in which the distance between pairs of electrodes is substantially equal to the thickness of the sacrificial spacer layer. Electrode arrays with gaps measured in units of nanometers are produced. In one embodiment, the first and second pluralities of electrodes are aligned in mutually orthogonal orientations.
