050122: Pneumatic Nano-Probe Tip for Nano-Manipulation and Manufacturing

A major problem with nano-manipulation is holding the target. Due to the lack of micro force/flow feedback, the target is often destroyed during its manipulation. It would be highly desirable to have a means for picking up and releasing nano-objects without the above difficulties. Description The current invention addresses current operational ...

050026: A Force Sensing Probe for Micromanipulation and Microassembly

A current limitation with existing micro-probe tips is their relatively high degree of bending when encountering objects on surfaces. This significantly limits the ability of micro-probes to manipulate micro-objects. In addition, the sensor can only have a small dynamic range in its bending if it is to maintain high accuracy in manipulating ob...

030073: Improved Force Sensing on Nano-Manipulated Objects

Efficient manipulation of nano-sized objects will require an effective means for sensing the force exerted by a nanoprobe on the object. Current PZT (lead zirconium titante)-based piezoelectric force sensors are limited in their sensitivity. Description By using a highly sensitive polyvinylidene fluoride (PVDF) piezoelectric force sensor to mea...
