Today’s soldiers require advanced capabilities to be effective on future battlefields. Advances in technology have produced better weapon optics, imaging devices, and body armor, as well as many other types of specialized protective and offensive gear. Body armor that could protect soldiers against rifle fire, for example, was not available during World War II, the
Inspired by the electric eel, researchers from the University of Fribourg in Switzerland have developed 3D-printed hydrogels that could generate up to 110 volts of electricity in an instant. The rows of gels contain positively and negatively charged ions that combine together to mimic the eel”s cellular structure. Unlike typical batteries, these systems are soft,
Remember those reports of exploding hoverboards a few years ago? The culprit behind those spontaneous electrical combustions were low-quality Li-ion batteries, which contain highly flammable, toxic, and moisture-sensitive electrolytes. A team of scientists at the Johns Hopkins Applied Physics Laboratory has partnered with researchers from the University of Maryland and the Army Research Laboratory to
