US research group develops world's smallest radio receiver

Abstract

Purpose

The purpose of this paper is to describe the world's smallest radio receiver, fabricated from a single carbon nanotube (CNT).

Design/methodology/approach

This paper describes the construction and mode of operation of the CNT radio and the experiments used to test its functionality.

Findings

It is shown that a single CNT can act as an antenna, adjustable tuner, amplifier and demodulator, resulting in a fully functional radio with the ability to receive and faithfully reproduce audio signals.

Originality/value

This paper describes the world's smallest radio receiver which has the potential to be used in a range of both conventional and novel applications.
