ALEXANDRIA, Va., March 24 -- United States Patent no. 12,582,332, issued on March 24, was assigned to Apple Inc. (Cupertino, Calif.).
"Piezoelectric sensor with resonating microstructures" was invented by Yindar Chuo (San Jose, Calif.) and Zijing Zeng (San Jose, Calif.).
According to the abstract* released by the U.S. Patent & Trademark Office: "A sensor system may have a force sensor formed from a piezoelectric film. The piezoelectric film may comprise a number of tuned microstructures that are configured to resonate at a particular frequency. In accordance with the tuning of the microstructures, frequency signals corresponding to the microstructure resonance may be mechanically amplified before being processed by associated processing e...
