Inspiration from nature

Inventors are finding a lot of inspiration from nature for new devices and robots of all types, and this one is particularly interesting and holds promise for future hearing devices. The structure of the fly's hearing organ in this case is very well-suited as a model for a better microphone that could be used in a hearing aid; the potential to be battery free is also good news for people who need these types of devices.

I love this kind of technology that exemplifies BEAM (biological, electronic, aesthetic, mechanical) robotics. Many non-natural signal processing methods have been made before that involve microcontrollers running programs, use of mathematic equations such as FFTs, phase detection algorithms. A fly knows nothing about Laplace and Fourier Transforms (nor do most people). But this device is more elegant in that it imitates nature and even generates the energy it needs. I would love to hear more about this as the project develops.

This device would also make an excellent motion sensor.

Thank you for shedding light on what kind of technology this is exactly, 78RPM. Yes, there is a lot of inspiration to be found in nature, that's for sure. I'll try to keep an eye on the project to stay on top of future developments.

Ah, that's an interesting concept, tekochip. So motion by hearing instead of actual motion detection, is that what you mean? That could work.

Ultrasonic motion detection is a method employed by many burglar alarm system, usually with a Piezo transducer.  The advantage, and disadvantage, over a PIR is that ultrasonic echoes from a single sensor can cover an entire room.

As a recent user of hearing aids, I appluad this kind of study. I was shocked at teh cost and life of my hearing aids. In this age of super electronics the cost and life expectancy were very disapointing. I think this research could lead to an affordable, long-lasting hearing aid. Just in time for the deaf boomers to use tehm.

I like your concept Tekochip. If I catch your drift, a burglar alarm with directional sense of sound or motion could surprise the guy (they're all men, right? What's wrong with men?) and shine a flashlight in his face in the night. This would either provoke a pseudo-violent attempt on his part or cause him to flee.  In either case, he'll flee upon awareness of his detection and probable photograph of his clothing and shape being uploaded to the cloud. Meanwhile, outdoor cameras would ... yadda yadda yadda.

I've always enjoyed that picture of you in the plane.  What kind of airplane is that? Is it yours? Many years ago I worked in engineering flight test at Cessna.  That's me on the left with my Great Dane in the truck.

Ultrasonic motion detection is a time honored technique.  What happens is that you send out an ultrasonic tone, and if the echo is a different frequency, caused by a Doppler shift, then you know that something is moving.
 
The plane is, indeed, my much-loved Cessna 172M.  That's very cool that you worked at Cessna, probably many years after mine rolled off the production floor.  Cessna has made more than 60,000 172s, with 7306 of the 172M, making it the highest production variant.  I'm proud to say that I soloed on N172SS.  Note the vanity tail number, 172SS was Cessna's test unit for the 172M.  The day I soloed I came home to an empty house with nobody to share my joy with.  I had to tell someone, so on a whim I sent an email to Captain Jim Lovell, and he wrote me back right away.

Cigarette companies are fighting back by buying up e-cigarette manufacturers.
