Capacitive Extensometer

The present invention provides for measurements of the principal strain magnitudes and directions, and maximum shear strain that occurs in a porous specimen, such as plastic, ceramic or porous metal, when it is loaded (or subjected to a load). In one embodiment the invention includes a capacitive delta extensometer arranged with six sensors in a three piece configuration, with each sensor of each pair spaced apart from each other by a predetermined angle, such as 120 degrees.

HemoCue ISS Tech Demo - Results and Lessons Learned

During long duration space missions, astronauts experience immune system dysregulation [1], and white blood cell (WBC) count can give vital information about the body’s immune response. The ability to measure WBC count is currently an unmet need on the International Space Station (ISS) and for future exploration missions. To address this need, the Human Research Program’s (HRP) Exploration Medical Capability (ExMC) Element, along with the Research Operations and Integration (ROI) Element and the NASA Johnson Space Center Immunology Lab, flew HemoCue®, a commercial-off-the-shelf analyzer with the ability to measure whole blood WBC count with 5-part differential to ISS in December 2020.
