Scientists have created “acoustic holograms” that can assemble matter into 3D objects, using just sound. The technique works with various types of particles and even living cells, allowing for a new kind of 3D printing that’s fast and contact-free.Cont… Continue reading “Acoustic holograms” quickly assemble objects from particles or cells
Engineers at the University of Minnesota have developed a new system that can move objects without making physical contact. The technique involves ultrasound waves acting on specialized surfaces to push or even pull objects in different directions, whi… Continue reading Ultrasound metasurfaces move large objects without touching them
While seabed-located cameras are great for tasks such as monitoring wildlife, powering them and retrieving their photos can be challenging. That’s where a new MIT-designed camera comes in, as it requires no battery, plus it wirelessly transmits its pho… Continue reading Battery-free MIT underwater camera is powered by sound
When it comes to communicating with one another while underwater, scuba divers typically use either hand signals or writing boards … both of which have limitations. Soon, however, they could be utilizing an app on their existing smartphone.Continue Rea… Continue reading Smartphone app transmits underwater messages between scuba divers
Traditional computer chips run on electricity, while the emerging photonic chips use light. Now, scientists at Harvard have demonstrated a new kind of chip that transmits data in the form of sound waves.Continue ReadingCategory: Computers, TechnologyTa… Continue reading Harvard’s acoustic computer chip uses sound waves to encode data
It seems inevitable at this point: our urban skies will soon teem with all manner of multicopter aircraft, from small logistics and delivery drones all the way up to eVTOL air taxis and minibuses. This will bring a lot of positives, including speed, co… Continue reading Acoustic awareness system could open the floodgates for drone delivery
One of eVTOL companies’ core promises is that these electric air taxis will be vastly quieter than helicopters – so quiet that we’ll be able to fill the skies with hundreds of them without subjecting city dwellers to brutal levels of added noise pollut… Continue reading NASA acoustic testing puts real numbers on Joby’s eVTOL noise signature
Consumer grade drones might be annoyingly buzzy when they’re close by, but detecting them at a distance has been challenging – especially considering their potential as weapons or surveillance tools, as well as their ability to shut down helicopter and… Continue reading Hoverfly vision circuits radically boost long-distance drone detection
The microphone is a pretty ubiquitous piece of technology that we’re all familiar with, but what if you’re not looking to record audio in the air, and instead want to …read more Continue reading DIY Hydrophone Listens in on the Deep for Cheap
Chinese company Lava surprised and delighted us with its “Me 2” carbon fiber acoustic guitar, and now it’s released “the first smart guitar ever,” with a built-in touchscreen to control several built-in effects and apps, including a tuner and looper.Co… Continue reading Lava unveils ambitious, lightweight Me 3 carbon fiber “smart guitar”
