Seiko Epson Corp. disclosed that its joint development effort with NGK Insulators Ltd (NGK) has succeeded in developing the world's smallest gyro-sensor.

According to a press statement, the XV-3500CB gyro-sensor boasts of unprecedented stability due to the use of a monocrystalline quartz crystal for the gyro element. By leveraging Epson's crystal microprocessing technology, low-power analog circuit technology and packaging technology, the joint development team was able to produce a gyro-sensor measuring 5-by-3.2-by-1.3mm.

Other features include a sleep mode that achieves both low power consumption and short startup time, and an airtight structure for excellent environmental resistance and 100 percent lead-free applications.

Operating between 2.7V and 3.3V, the subminiature angular velocity sensor has a 1.35V output in stationary state, 100/s detection range, 0.67mV//s sensitivity, and 5 percent FS linearity. Designed for systems that correct camera vibrations, the device will enable compact digital cameras, camera-phones and other products to be equipped with a high-performance motion correction feature.

The new gyro-sensor is scheduled to enter volume production in December 2004.
