CHAPTER.1 INTRODUCTION For decades‚ scientists have been using electromagnetic and sonic energy to serve medicine. But‚ aside from electro surgery‚ their efforts have focused on diagnostic imaging of internal body structures—particularly in the case of x-ray‚ MRI‚ and ultrasound systems. Lately‚ however‚ researchers have begun to see acoustic and electromagnetic waves in a whole new light‚ turning their attention to therapeutic—rather than diagnostic—applications. Current research is exploiting

message contents. A headphone is used to hear the detected signals. Project Description The circuit schematic is given in the .rar archive attachment. There are two separate detector units. Every detector unit consists of a dipole antenna‚ a choke and a diode. The antenna receives the GSM signals in media. Then a small amount of charge is induced in the choke. The diode demodulates the signal and finishes detecting. The diodes must be schottky diodes or germanium diodes. Since the forward voltage of
