As part of a NEDO project, Toshiba Shomei Precision Corporation, Tohoku University and Piezo Studio Inc. developed a resonator with a new Langasite-type crystal and achieved low-cost commercialization by establishing new manufacturing processes ranging from crystal growth to device fabrication.

Compared to a traditional quartz resonator, this resonator has low impedance with a short start-up time, as well as having a high bandwidth, contributing to power-saving and miniaturization of onboard equipment. In the future, the resonators are expected to be applied to a range of new applications, such as use in high-bandwidth filters.
