Startup Unveils Cheaper Fingerprint Scanner
Fidelica Microsystems has developed a unique sensor that measures the difference in pressure between the ridges and valleys of a fingerprint, which the company claims makes it more reliable than traditional devices.A Silicon Valley startup on Monday will unveil new fingerprint-scanning technology that company officials say is far cheaper and more reliable than traditional scanning devices. Fidelica Microsystems Inc. has developed a unique sensor that measures the difference in pressure between the ridges and valleys of a fingerprint. Traditional fingerprint-scanning devices use a light source to measure the distance between the scanner and the finger, but the results can be fouled by moisture, dirt or other substances on the finger.
Fidelicas sensor is about the size of a postage stamp and comprises thousands of tiny sensing cells. Unlike other sensors, which utilize semiconductors made from silicon wafers, the Fidelica devices are manufactured using glass substrates, a much cheaper process, according to K.G. Ganapathi, president and CEO of Fidelica, based in Milpitas, Calif.
