Finger-input Touch Authentication using Physical Vibration (VibWrite)
Invention Summary:Researchers at Rutgers University have created an innovative authentication system named VibWrite. The system places an inexpensive vibration motor and receiver on a solid surface, such as wood, metal, plastic, glass (e.g., a door panel, a desk or an appliance). The motor sends vibrations to the receiver. When a user touches the surface...

GOLD NANOSTAR SUBSTRATES FOR SERS SENSING IN THE FEMTOMOLAR REGIME
Invention Summary:Raman spectroscopy is a valuable analytical tool that employs vibration patterns for the identification of molecules. However, it is limited due to the low scattering cross section of most Raman active molecules, which leads to low sensitivity. Surface-enhanced Raman spectroscopy (SERS) increases the intensity of Raman signals by leveraging...
