The Micro Sensor 1.8™ is one of the latest breakthroughs from Polhemus, the leaders in motion measurement innovation. This 6DOF (6 Degree-Of-Freedom) micro sensor tracking element utilizes Polhemus proprietary AC electromagnetic technology, weighs in at less than a gram, and measures only 1.8 millimeters in OD (outer diameter). Micro Sensor 1.8 comes in Standard and Flex models, for a less rigid cable option. Shown above on left, Micro Sensor 1.8 Flex is attached with optional custom Micro Mounts, allowing the sensor to slide through easily and keep sensors in place; on right, Micro Sensor 1.8 shown in hand.
Small and lightweight, it packs an enormous amount of capability into its small size and provides both position and orientation data, at speeds up to 240 Hz (frames of data per second).
Like all Polhemus tracking technology, the new Micro Sensor 1.8 requires no line-of-sight to continuously track its position and orientation. Better still, Polhemus sensors are completely embeddable into a variety of custom form factors, ideal for fitting inside a traditional catheter, a head-worn device, such as an HMD, simulated medical tools, or even slipped under gloves or clothing. This makes the Micro Sensor 1.8 an ideal tracking solution for applications requiring not only high-fidelity precision tracking, but also small-scale sensor size.

"I just received1 my LIBERTY 8 system and I am extremely pleased. Our records are clean and precise. The system is robust, with no crashes at all with the AuSIM drivers for Matlab and USB interface. Our previous magnetic system crashed within Matlab on a regular basis." - H.N. Zelaznik, Professor of Health and Kinesiology, Purdue University
