The nano radio is a remarkable break through development that will that have wide ranging repercussions in multi various fields from the detailed study of body living cells sensor applications, drug delivery to cancer affected cells ,control device small enough to exist in a human’s blood stream, and of course playing music and favorite songs and many more applications. Nano radio is a fully functional, fully integrated radio receiver from a single walled nano tube. The nano tube serves simultaneously as all essential components of a radio: antenna, tunable band pass filter, amplifier and demodulator. A direct current voltage source as applied by a battery powers the radio. Using the carrier waves in the commercially 40-400 MHz range and both frequency and modulated techniques it demonstrated successfully. The white paper reveals about the working of a nano radio with carbon nano tube and electrodes. The carbon nano tube plays a very crucial role in the operation of a nano radio. The multi usage of the single walled carbon nano tube as an
antenna , tuner, amplifier and demodulator. The differences between the working of a normal radio and a nano radio can be explained. Any wireless device from cell phone to environmental sensors could benefit from nano radios .Smaller electronic components such as tuners ,would reduce power consumption and extends battery life. Nano radios could also steer wire less communications into entirely new realms , including tiny devices that navigate the blood stream to release drugs on command. Nano radios has exciting application areas and opens many possibilities of applications from treating malignant cancer cells to studying the body cell functions ,home pregnancy resting kits, hearing aids ,cell phones ,I phone and many more are yet to come in the future. Continuous research and developement are carried out by many firms and universities through –out the world.
At the core of the nano radio is a single molecule that can receive radio signals. It was developed by Alex Zettl at the university of California, Barkeley . Introduction:
Radio has had a profound applications on civilization from its early use in critical communications such as with ships at sea , to its later use during the “golden age “ of radio in the 1930’s as a mass medium for news and entertainment, and finally to it’s more recent use in cellular phones and wireless computer networks and the global positioning system. Historically applications of radio have been tightly linked to available technology. Early spark gap receivers were only capable of receiving on – off signals such as morse -code. Vacume tube technology enabled cheap and reliable audio communication .Perhaps more strikingly the solid state transistor transformed the radio from a bulky, power hungry and stationary unit to a device that could be carried in a shirt pocket. To day the same silicon based technology that gave us the transistor is fast approaching hard physical limits , and it is expected that future progress will require new nano scale materials such as carbon nano tubes.Combining the many of the unique electrical and mechanical properties of the carbon nano tubes a fully functions radio receiver have fabricated ,orders of magnitude smaller than previous radios from a single carbon nano tube. The carbon nao tube radio may lead to radical new applications such as radio...
