The change of electrical resistance of a highly extensible composite sensors consisting of a network of entangled multi-wall carbon nanotubes (CNTs) and thermoplastic polyurethane elastomer in the course of elongation was stimulated by initial tensile deformation. Though the initial deformation irreversibly changes the arrangement of CNT network, subsequent cyclic elongation and corresponding resistance...
Today's high functionality electronic circuits require faster interconnection speed, better thermal conductivity and the good mechanical properties for reliability. These requirements calls for enhanced properties of the present solder materials. Appropriate reinforcements in the existing solder material will help in achieving much improved electrical, mechanical and thermal properties. Carbon Nano...
Carbon nanotubes (CNTs) have been attractive materials because of the unique combination of their small size and physical properties, such as high thermal conductivity and mechanical compliance. This paper extracts in-plane modulus of 100–220 µm-thick vertically aligned multi-walled carbon nanotube (VA-MWCNT) films. The films have low modulus in the range of 0.5–2 MPa, consistent with expectations...
Densely packed carbon nanotube (CNT) forest on silicon wafer has been fabricated by combining the process of mechanical press and liquid densification. Advantages from the densely packed CNT forest prototype devices include: (1) 16-fold volume reduction with the same amount of CNT forest as compared to the as-grown CNT forest; (2) preservations of aligned CNT organization and natural contacts to the...
This paper reports a new class of biosensors based on composite nanomaterial thin film. The composite nanomaterial film is synthesized using a simple vacuum filtration method. Using composite nanomaterial film, we can not only simplify the positioning and integration fabrication process of nanoscale materials into a functional device, but also enhance the sensing surface area significantly, which...
As we know, the unsatisfactory field emission from the films by electrophoresis is resulted from the weak adhesion. The main aim of this paper is to improve the adhesion surrounding electrophoresis technologies. In addition, A simple controllable method is reported for the coating of ZnO nanowires with Ag nanoparticles and ZnO/Carbon nanotubes (CNT) composite.
Numerous studies have been conducted to date on field emission from carbon nanotubes (CNTs). For CNT film, there were two main methods: direct growth of CNTs onto a substrate, post-treatment to make CNTs adhered onto substrate. In this work, the adhesive taping method was adopted to improve the stability and reproducibility.
This paper demonstrates a novel flexible carbon nanotubes (CNTs) electrode array for neural recording. In this device, the CNTs electrode arrays are partially embedded into the flexible Parylene-C film using a batch microfabrication process. Through this fabrication process, the CNTs can be exposed to increase the total sensing area of an electrode. Thus, the flexible CNTs electrode of low impedance...
As we know, the unsatisfactory field emission from the films by electrophoresis is resulted from the weak adhesion. The main aim of this paper is to improve the adhesion surrounding electrophoresis technologies. The technique we applied is referred to employ both organic binders and inorganic solution simultaneously. In addition, the influences of the applied voltage, inter-electrode distance and...
The composite structure of silicon tips and vertical aligned carbon nanotubes (CNTs) was prepared using plasma enhanced hot filament chemical vapor deposition (PE-HFCVD) method on the silicon wafer, and Au/Ni film coated on the substrate was considered as a catalyst. High proportion hydrogen of 96% volume percentage and high total pressure are used during preparing process, and the pure CNTs, pure...
