[mems-talk] Probe Arms with Kinematic bearings? Where to buy it?

[Guangchi Archie Xuan]

Hi, All,
       Thinking of building a probe arm with probe tips at the end for electrical measurements that can apply constant force on a flat surface. The arm can only have one degree of freedom (rotating along the horizontal axis). I read that the Kinematic bearing arms will achieve that. But where to buy this kind of things? Thank you!
