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.

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

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.

This device would also make an excellent motion sensor.

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.

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.
