Electronic, inexpensive, low-power gas sensors are based on single-walled carbon nanotubes (SWCNT) and provide a method for gas detection by coating or doping the SWCNTs with suitable materials. Applications include detection of flammable gases for the petrochemical industry, methane detection for the mine safety industry, environmental monitoring of toxic industrial gases, and monitoring gases in a patient’s breath.

Lightweight Fiber Optic Sensors for Real-Time Strain Monitoring

A lightweight, robust fiber optic sensor system can be used to calculate a variety of critical parameters, including shape, stress, temperature, pressure, strength, and operational load. This system processes information at rates of 100 times per second, enabling real-time strain measurements to determine the shape of an aircraft’s wing, monitor the structural integrity of bridges and pipelines, or ensure precise placement of the tiniest catheters.

Compact Full-Field Ion Detector System (CFIDS)

CFIDS is a radiation particle detection system that provides information on the kinetic energies, directions, and electric charges of subatomic particles. It consists of a spherical Cherenkov detector, a compact detector stack, and low-noise, large-area detectors based on silicon carbide. The technology could be used for radiation dosimetry aboard high-altitude aircraft and in proton radiation therapy for cancer treatment.

Advanced Gas Sensors and High-Temperature Pressure Sensors

Advanced hydrogen and hydrocarbon gas sensors are capable of detecting leaks, monitoring emissions, and providing in-situ measurements of gas composition and pressure. These sensors can be used to optimize combustion and lower emissions, and are designed to withstand high-temperature environments. Applications include leak detection for hydrogen-powered vehicles, engine emissions monitoring and control, and fire detection and environmental monitoring.

High-Precision Electric Gate (HPEG) for Time-of-Flight (TOF) Ion Mass Spectrometers

This mass spectrometer studies the magnetosphere of Jupiter and Europa. The HPEG can provide a precise “start” pulse when an ion enters the TOF section of an ion mass spectrometer to provide a very high-mass resolution capability. It is small and light for spaceflight or portable mass-spectrometry applications.

Passive Smart Container

A passive smart container monitors and tracks items that are too small to tag on an individual item level. It uses RFID circuits to identify the fill level in a container, and could be converted for use in industries such as individual health care management, pharmaceutical manufacturing, distribution inventory tracking, and retail and supply chain inventory management. Users can manage and control an inventory of small items and small electronic components.

Biomarker Sensor Arrays for Microfluidics Applications

A method manufactures biomarker sensor arrays with nanoscale resolution and active regions on the order of 1 micron by applying nanolithographic direct-write techniques to the fabrication of silane chemistry sensors on a transparent substrate. The invention can be applied to formation of patterns using biological materials, chemical materials, metals, polymers, semiconductors, small molecules, organic and inorganic thin films, or any combination of these.
