Mechanophore-Grafted Polymers to Form Stress-Responsive Thermoset Network
Identifying damage detection is critical in many industries to reduce catastrophic failure. Mechanochemistry is the study of stress-responsive molecular units that sense force changes in their local environment to allow for determination of the stress, strain, or damage applied. Certain mechanophores have a florescent emission when undergoing stress....

In-situ damage detection system for mechanpohore-embedded fiber reinforced composites
Composites often fail due to mechanical wear, abrasion, friction and stress they experience during use. Mechanophores have emerged as a strategy for detecting damage caused by these mechanical loads. Mechanophores embedded in composites undergo a chemical reaction when significant damage occurs and typically change to a fluorescent color as a signal...

MET Based Accelerometer Using Ethylammonium Nitrate (EAN) Based Potassium Iodide Droplets as the Sensing Body
Molecular Electronic Transducer (MET) seismometer cells are inertial sensors which detect motion based on the movement of liquid electrolyte between electrodes. A MET sensing element consists of electrodes with spacers that are suspended across a narrow channel containing a liquid electrolyte. Holes through the electrodes allow electrolytes to flow...

Responsive Dynamic Three-Dimensional Tactile Display (System)
The most common interface between electronics and humans is a keyboard and optical display, thus modern electronics are largely visually based. However, for the visually impaired, this interface has fundamental limitations. Because of this, the percentage of visually impaired people who use computer electronics is low. Voice systems were created to...
