Philly-based Drexel University was founded in 1891 as the Drexel Institute of Art, Science and Industry by Philadelphia financier and philanthropist Anthony J. Drexel to provide educational opportunities in the "practical arts and sciences" for women and men of all backgrounds.
Today Drexel has some 16,000 students, and 145 U.S. patents and patent apps, take a look at them here. [see all U.S. University Patent Portfolios here]
Most recently Drexel inventors won ALL-ELECTRIC PIEZOELECTRIC FINGER SENSOR (PEFS) FOR SOFT MATERIAL STIFFNESS MEASUREMENT from 6/11/09, U.S. Patent Application 20090145246--
A PEFS (Piezoelectric Finger Sensor) acts as an “electronic finger” capable of accurately and non-destructively measuring both the Young's compression modulus and shear modulus of tissues with gentle touches to the surface. The PEFS measures both the Young's compression modulus and shear modulus variations in tissue generating a less than one-millimeter spatial resolution up to a depth of several centimeters. This offers great potential for in-vivo early detection of diseases. A portable hand-held device is also disclosed. The PEF offers superior sensitivity.
