Radio Frequency Cochlea perceives signals million times fold than human ears
Cochlea is a part of the human inner ear. It is a spiral-shaped, fluid-filled inner ear structure; it is lined with cilia (tiny hairs) that move when vibrated by sound waves and cause a nerve impulse to form. And it is exciting to note that a particular researcher took notice of this powerful membrane.
MIT researchers, Rahul Sarpeshkar, associate professor of electrical engineering and computer science, and graduate student Soumyajit Mandal designed the chip to mimic the cochlea. According to them, they have developed a fast, ultra-broadband, low power radio chip that works like the human cochlea (as described in a paper published in the June issue of the IEEE Journal of Solid-State Circuits).
The RF Cochlea is "embedded on a silicon chip measuring 1.5 mm by 3 mm, works as an analogue spectrum analyser, detecting the composition of any electromagnetic waves within its perception range. Electromagnetic waves travel through electronic inductors and capacitors (analogous to the biological cochlea's fluid and membrane). Electronic transistors play the role of the cochlea's hair cells", Sarpeshkar said.
The RF Cochlea could enable wireless devices to receive radio signals for cell phones, portable digital radios and televisions.

This is great to learn that science and technology is developing so much that they are now mimicking human body parts. It will help a lot in many fields in future.
It is a very interesting blog about artificial intelligence. I read it with wonder and it is fantastic. God bless you.
i wish to congratulate the reasearchers for their great invention like this. Thanks william for posting a great article like this and it is easily understandable.
This is very usefull information to me. the pictorial representation is also very nice. It ios very usefull to the students.Thank you.
