The small but powerful Micro Sensor 1.8 is a tiny motion tracking sensor that tracks in full 6DOF (Degrees- of-Freedom), capturing precise measurements of both position and orientation, and delivering tracking speeds up to 240Hz.

Small Matters

Weighing in at less than one gram, and boasting a slender size, at 1.8mm OD (Outer Diameter), Micro Sensor 1.8 is ideal for attaching to objects, such as surgical and dental instruments, and more. Micro Sensor delivers high-fidelity tracking that can measure the slightest movement of a skilled surgeon, or the robust fingers of a world-class guitarist. This tiny sensor can be inserted into a catheter, and is completely embeddable, while maintaining full 6DOF tracking.
