“…This method has also been followed up more recently by Hierold and co-workers [7], however, it requires complex fabrication technology and complicates the integration of the grown nanotubes. We have recently reported a related but simpler technique [8] involving the direct growth of nanotubes on metal electrodes fabricated on a silicon chip.…”

We use a highly localised resistive heating technique to grow vertically aligned multiwalled nanotube films and aligned single-walled nanotubes on substrates with an average temperature of less than 100 o C. The temperature at the catalyst can easily be as high as 1000 o C but an extremely high temperature gradient ensures that the surrounding chip is held at much lower temperatures, even as close as 1µm away from the local heater. We demonstrate the influence of temperature on the height of multi-walled nanotube films, illustrate the feasibility of sequential growth of single-walled nanotubes by switching between local heaters and also show that nanotubes can be grown over temperature sensitive materials such as resist polymer.PACS: 61.46.Fg Nanotubes.

“…4(a), the capacity for every user C I u−sym in bit/symbol, obtained from (5), (6) and (8) in (18), is shown as a function of the number of interfering users in the system U and transmission distance d. For a low number of interfering users, the capacity behaves with distance similarly to the single-user case studied in Sec. IV-C.…”

“…INTRODUCTION Nanotechnology is providing a new set of tools to the engineering community to design and manufacture integrated devices just a few hundred of nanometers in size. One of the early applications of these nano-devices is in the field of nanosensing [24], [14], [6]. Nanosensors are not just tiny sensors, but devices that take advantage of the properties of novel nanomaterials to identify and measure new types of events in the nanoscale, such as chemical compounds in concentrations as low as one part per billion [17], [15], or the presence of virus or harmful bacteria [23], [19].…”

“…Nanowire, nano-resonators, and nano-rods are finding their ways in complex medical diagnostic applications. Carbon nanotubes (CNT) can be used to develop electromechanical sensors for implantable devices which can be used in minimal invasive diagnosis, health monitoring, drug delivery, and many other intra-corporal tasks [50]. d) ASIC Developing application specific integrated circuits (ASIC) for specific applications can optimize the sensor performance but the associated cost can be very high which makes it suitable for applications where size and performance are the deciding factors rather than the price.…”

With the advancement of ubiquitous computing under the hood of Internet of Things (IoT) and Cyber-Physical Systems (CPS), the number of connected devices is expected to grow exponentially in the following decade. Pervasive sensing is the backbone of any IoT/CPS application. Billions of connected devices each having multiple sensors will lead us to the age of trillion sensors. Widespread use of sensors in critical applications (e.g., smart grid, agricultural industry, food production, etc.) will present us with unique challenges. Identifying the threats well before they occur will be the key in the race against the threats posed by the adversaries in the age of trillion sensors (TSensors). In this paper, we present a detailed survey of the trends toward trillion sensors, and their applicability in recent connected applications. We identify several key areas, that need to be addressed to build a secure connected environment. There are several challenges and limitations as well which are expected to rise in the coming decade. We must be proactive in addressing those challenges to make a safe and secure environment.
