Motion Sensing Technology
Motion sensing technology created by combining crystal device and semiconductor technologies
Combining and advancing the strengths of both businesses
Epson's roots are in its watch business. To achieve innovative watches, we began developing and manufacturing our own quartz crystals and integrated circuits. Today, Epson is the rare company that has both a crystal device business and a semiconductor business.
This unique business structure enables us to create highly accurate sensors and is a source of strength that separates us from the competition. Epson's unique QMEMS (quartz + micro electro mechanical system) fabrication technology allows us to realize a variety of extremely small, frequency stable quartz crystal devices that are essential in electronic equipment.
