Smallest Sensors
1. Epson (uFR-II)
Advanced Model of World's Smallest Flying Microrobot from Epson (August 2004)
• Micromechatronics technology• The world's new lightest and most advanced
microrobot• The uFR-II is only the latest chapter in an Epson
success story that began with Monsieur, a microrobot that was listed in the Guinness Book of Records as the world's smallest microrobot.

• The device, the KXPS5, is just 0.9 millimeters thick, The sensor measures acceleration and is
primarily used for free-fall detection in hard drives.
• The KXPS5 family of products was specifically engineered to have a very small form factor so that they can be incorporated directly into the hard disk drive.
• use specifically in the hard drives of mobile-electronic devices such as cell phones and iPods.
