Measuring only 3mm x 3mm and 1mm high, ST’s new L3GD20H gyroscope enables advanced product miniaturisation by occupying a little over half the volume of its predecessor while offering better resolution, higher accuracy, superior stability and faster response time.
The small gyroscope enables smaller sensing mechanisms in smart consumer electronics including mobile phones, tablets, game consoles, digital cameras and industrial tools.
The ultra-small dimensions of the new gyroscope also bring experimental projects such as wearable electronics closer towards true practicality. One such project is the prototype smart suit that ST used to demonstrate inertial body-motion reconstruction early in 2012, which can help enhance various applications such as augmented reality, sports training aids, or medical therapy.
Roberto De Nuccio, Business Development Manager for ST’s Motion MEMS Division explains that miniaturised low-power sensors such as the new L3GD20H enable smart electronics to be used in ever-smaller and slimmer handheld devices as well as in items such as clothes or sports equipment, creating opportunities for exciting new products and services.
He adds that the tiny MEMS devices will benefit both high-volume applications in smartphones and tablets as well as emerging applications such as prosthetics, medical instruments, goods tracking and power tools.
The new gyroscope retains a similar register structure as its predecessor (L3GD20), making it easy for designers to reuse existing software code, reduce time to market and lower development costs. Designers will also benefit from ST’s Sensor Fusion development environment.
ST’s MEMS gyroscopes as well as accelerometers, magnetometers and iNEMO inertial modules enable innovative products and apps such as context-sensitive user interfaces, augmented reality, kinetic gaming, and industrial solutions including container tracking or emergency-stop mechanisms.
Key features of ST’s L3GD20H MEMS gyroscopes:
