Scientists invent 'Luciola', a floating light weighing just 16.2 mg
According to Japanese scientists, they have developed a tiny wireless electronic light, roughly the size of a firefly, which keeps afloat using ultrasonic waves and could potentially be used in several applications ranging from projection mapping to moving displays. The device, created by the Kawahara Universal Information Network Project, has been named 'Luciola' for its resemblance to a firely. Here's more about 'Luciola'.
'Luciola' - A wonder creation
Named Luciola, this minuscule light took 2 years for the scientists to create it. The light, weighing just 16.2 mg, has a diameter of 3.5 mm and emits a tiny halo of red gleam. Luciola is powered by 285 microspeakers that emit ultrasonic waves to keep it afloat and with a frequency inaudible to humans, these microspeakers allow Luciola to operate in total silence.
Created today, for tomorrow!
The developers believe Luciola can find applications in IoT devices which get connected to networks to send and receive data such as cars, or other domestic appliances or smartphones. The light can be equipped with temperature or motion sensors to find novel uses or can be used to make moving displays with several lights put together or projection mapping events, given the light's potential.
