Latest Patents

One of Youn's latest patents is a MEMS acoustic sensor. This innovative sensor includes a substrate and a cavity, with a back plate supported on the substrate that features a plurality of through-holes. It also has at least one anchor projecting from the back plate toward the substrate, and a diaphragm supported by the anchor that deforms in response to sound waves entering through the cavity. Notably, no part of the deformed diaphragm comes into contact with the substrate, enhancing its functionality.

Another significant patent is a method and apparatus for authenticating fingerprints using reflected waves. This technology is designed to determine whether a fingerprint is forged or falsified by utilizing a waveform reflected from the subject, such as an ultrasonic wave. The fingerprint authentication apparatus includes a sensor that applies a wave signal to the subject and receives the reflected wave signal. It features a local waveform detector that detects local waveforms by dividing the received signal over time, and a forgery detection unit that counts the number of local waveforms to ascertain the authenticity of the fingerprint.
