Epson has manufactured and sold crystal devices, components essential for controlling electronic equipment and other tasks, since the 1960s. Devices made from crystal are known to provide temperature stability and possess other fundamental properties that are superior to those of devices made from ceramics and other materials. Epson uses these crystals in products such as gyroscopic sensors that accurately sense and correct for camera shake, and pressure sensors that detect even very slight changes in pressures.
Here you can learn about Epson's proprietary QMEMS^* technology (essential for producing tiny yet powerful crystal devices), sensors made using crystal, and system products that incorporate these sensors.
