Japanese Scientists Invent a Light Weight Floating ‘Firefly’ Luciola

Japanese Scientists Invent a Light Weight Floating ‘Firefly’ LuciolaJapanese engineering researchers have created tiny wireless LED lights about the size of a firefly which levitates in the presence of ultrasound and could potentially figure in applications ranging from projection mapping to moving displays.

The featherweight levitating device has been named ‘Luciola’ for its resemblance to a firefly. ‘Luciola’s every hemispherical particle has a diameter of 3.5mm, weighs 16.2mg, and emits a tiny halo of red that can illuminate the text.

According to University of Tokyo researchers, this minuscule light “Luciola” is powered by 285 micro speakers that emit ultrasonic waves to hold up the light and have a frequency inaudible to humans, these micro speakers allow Luciola to operate in apparent total silence.

It took two years to create this wonderful creation “Luciola”, said the creator and the developer of the device Makoto Takamiya, a scientist at Kawahara Universal Information Network Project.

The developers believe Luciola has potential to find applications in the so-called Internet of Things devices, in which regular objects need a network to get connected and to send and receive data, such as cars, or domestic appliances such as air-conditioners, smart TVs, and Phones.

This minuscule light is equipped with movement or temperature sensors, which make Luciola find novel users to deliver a message or to make moving displays with multiple lights put together and can detect the presence of humans, or participate in futuristic projection mapping events.

The scientists at the Kawahara Universal Information Network Project a part of the Japan Science and Technology Agency hope Luciola will be commercially viable in 5-10 years for use in moving displays.

Professors at the University of Tokyo hope that such tiny objects will have smartphone capabilities and have potential to float about helping in our day to day lives in much efficient and smarter way.
