We have attempted to observe straining responses of an individual multi-walled carbon nanotube (MWNT) by performing an in-situ tensile testing inside scanning electron microscope (SEM). The both ends of an individual MWNT was attached on the rigid support and the tip of the force sensor using electron beam and was elongated by a nano-manipulator. The nano-manipulator was automatically controlled by personal computer. Linear deformation and fracture behaviors of MWNT were successfully observed and its force-displacement curve was also measured from the bending stiffness and displacement of the force sensor and manipulator. The tensile properties of individual MWNT were evaluated from the tensile test results.

Torsional Balance

The torsion balance, consisting of a rigid balance beam suspended by a fine thread, is an ancient scientific instrument, yet it is still a very sensitive force sensor to date. As the force sensitivity is proportional to the lengths of the beam and thread, but inversely proportional to the fourth power of the diameter of the thread, nanomaterials should be ideal building blocks for torsion balances. Here, we report a torsional balance array on a chip with the highest sensitivity level enabled by using a carbon nanotube as the thread and a monolayer graphene coated with Al nanofilms as the beam and mirror. It is demonstrated that the femtonewton force exerted by a weak laser can be easily measured. The balances on the chip should serve as an ideal platform for investigating fundamental interactions up to zeptonewton in accuracy in the near future.

Walled Carbon Nanotubes

The structure of carbon nanotubes is recognized to be suitable for medical applications such as encapsulating drugs or genes with the aim of targeted deliveries. In this regard, knowing about the suction force exerted on a nonoscale object which is supposed to be sucked into a carbon nanotube, and whether the object is accepted by the carbon nanotube are important issues to be studied. In this chapter, considering the nanoscale object as a carbon nanotube, a new semi-analytical method is developed to determine the van der Waals interaction between two concentric single-walled carbon nanotubes.

And Control

We developed a novel catheter operating system with an integrated force sensor for medical applications which included a highly precise master-slave remote control system. This paper explains the system design and control system in detail. As part of our research, we designed a micro force sensor and included it in the system to ensure safe operation in intravascular neurosurgery applications. We performed operation simulation experiments and analyzed the operating errors. The experimental results indicated that the proposed force sensor-based catheter operating system works well and can be controlled remotely, and the force feedback can effectively improve operability at an aneurysm.
