A scholar from Iran has built the worlds’ tiniest microphone. Bahram Azizullah Ganji who is a faculty member at the Noshirvani University of Technology in Babol Iran has given the tiniest capacitor microphone ever built to the world. The dimensions of the microphone are 0.5 mm x 0.5 mm. The microphone is so tiny that it cannot be viewed by your naked eye.
Its size cannot hide its projected use. These microphones will be a blessing to people with hearing problems because of their sheer size. Among other features of these microphones is high sensitivity, low cost and low power consumption. The benefits of these microphones will be of great help to medical science. For doctors, these microphones will be useful in receiving the exact sound of the heart for diagnosis of heart problems and examinations of foetus health.
The microphone can also be useful in fishing and surveillance systems under water to measure the sound waves and ultrasound waves to identify different marine animals. In addition to this, the microphones will be useful in telecommunication systems, information collection devices and defence systems.
The Iranian scientist feels that this microphone could be used as an invisible hearing aid. Ganji is working on the design and fabrication of nano electronics. He intends to introduce this microphone into the mainstream market at a really low cost. It can be fit on the top of a pen or adjusted on the spectacles to be used for information collection.
