Important Innovations

  3D Printed Alternative to Needles                                                                 Source:  UNC-Chapel Hill New Tech That's a Breakthru for Vaccines Researchers at Stanford University and the University of North Carolina-Chapel Hill have developed a 3D printed plastic patch as an alternative to COVID-19 vaccinations by needles.  The patch contains an array of microneedles that directly deliver the vaccine into the skin.  The researchers say the microneedle patch is ten times more effective in producing an immune response than a needle and it is painless. Microneedle patches have been under development for decades.  But the breakthrough on this revolutionary new patch came from 3D printing the microneedles on a polymer patch just long enough to reach the skin ...

Tracks Up to 12 Miles Source:  KAUST Potential for Personal Security, Health, Drones, Self-Driving Cars A tiny, low cost radar developed by an international team of scientists offers better navigation.  Developers in Saudi Arabia and Finland say it could serve as an avoidance system for unmanned drones and self-driving cars.  It could also be used as part of navigation systems for the visually impaired. They add it has potential for personal security and health care applications. KAUST and VTT The new radar device was created by researchers at the King Abdullah University of Science and Technology (KAUST) in Saudi Arabia and VTT Technical Research Center in Finland.  The device weights less than 150g and is powered by a 5V battery.  The team says it provides detailed information on the size, distance and speed of moving objects.  The tracking range is up to 12 miles.  Current radar are large and bulky. They tend to lose key detail informatio...
