WIRELESS NANOSENSOR NETWORKS USING GRAPHENE-BASED NANO-ANTENNAS : CASE STUDIES PAPER. DINESH. V Assistant Professor of Physics. Government First Grade College, Sagar-577 401, Shimoga-Dist. Karnataka. E-mail: dinu.v18@gmail.com ABSTRACT Nanotechnology is enabling the development of devices in a scale ranging from one to a few hundred nanometers. At this scale, novel nanomaterials and nanoparticles show new properties and behaviors not observed at the microscopic level. The aim of nanotechnology is on creating nano-devices with new functionalities stemming from these unique characteristics, not on just developing miniaturized classical machines. One of the early applications of nanotechnology is in the field of nanosensors . A nanosensor is not necessarily a device merely reduced in size to a few nanometers, but a device that makes use of the unique properties of nanomaterials and nanoparticles to detect and measure new types of events in the nanoscale. For example, nanosensors can detect chemical compounds inconcentrations as low as one part per billion the presence of different infectious agents such as virus or harmful bacteria. Communication among nanosensors will expand the capabilities and applications of individual nano-devices both in terms of complexity and range of operation. The detection range of existing nanosensors requires them to be inside the phenomenon that is being measured, and the area covered by a single nanosensor is limited to its close environment. A network of nanosensors will be able to cover larger areas and perform additional in-network processing. In addition, several existing nanoscale sensing technologies require the use of external excitation and measurement equipment to operate. Wireless communication between nanosensors and micro- and macro devices will eliminate this need. For the time being, it is still not clear how these nanosensor devices will communicate. We envision two main alternatives for communication in the nanoscale namely, 1. Molecular communication 2. Nano-electromagnetic communication.
