Physical Sensors
NASA is developing innovative harsh environment physical sensing and instrumentation technologies to advance next-generation space exploration, science, and aeronautics research.
Overview
Novel Film Sensors
Developing robust thin film sensors with ceramic, laminate and nanostructured materials onto complex components.
NASA’s Glenn Research Center in Cleveland has an in-house effort to develop thin film sensors for surface measurement in propulsion system research. The sensors include those for strain, temperature, heat flux and surface flow, which will enable critical vehicle health monitoring and characterization of components of future space and air vehicles. This technology can also be applied to characterize the harsh environment on planetary surfaces.
The use of sensors made of thin films has several advantages over wire or foil sensors. Thin film sensors do not require special machining of the components on which they are mounted, and, with thicknesses less than 10 μm, they are considerably thinner than wire, foils, or spray-on sensors. Thin film sensors are less intrusive to the operating environment than traditional sensors, and therefore have a minimal impact on the physical characteristics of the supporting components.
Micro-Photonic Techniques
Investigating novel new micro and nanoscale methods for miniature sensing and unobtrusive measurements.
Optical Trapping
Optical trapping, also known as optical tweezers, use light from lasers to trap and manipulate microscopic objects. Development of optical trapping techniques provides a tool that can be used for microscopic construction of specialized sensors, materials, and for the transport of microscopic quantities of materials for processing.
Morphology Dependent Resonances
Morphology dependent resonances (MDR), also known as whispering gallery modes (WGM), are resonant phenomena that extract portions of an incident electromagnetic field and trap them inside a round cavity. These resonances can be used for a variety of applications including very fine scale monitoring of temperature, force, pressure. They can also be used for optical switching, optical signal processing and sorting, and for chemical species concentration.

Temperature Probe for Measuring up to 2400°C
This technology is for a probe that uses multi-wavelengths to measure very high temperatures, from 1380°C up to 2400°C. The ability to withstand higher temperatures and oxidizing atmospheres translates into extended lifetimes even during operation in less severe conditions.
High-Temperature Thin-Film Strain Gauges
NASA Glenn has developed high-temperature thin-film strain gauges, which are miniature and deposited directly on the test articles. These sputter-deposited thin-film resistance strain gauges can provide minimally intrusive surface strain measurements in the temperature range from ambient up to 1100°C.

Fission Surface Power
The solar system does not provide easy access to electricity as we know it on Earth. Astronauts could take advantage of a reliable power supply to explore both the Moon and Mars. The system will need to be lightweight and capable of running regardless of its location, the weather, or available sunlight and other natural resources.
