Claims of a mysterious "sonic weapon" used in Venezuela fuel speculation about exotic U.S. military technology, though ...

Acoustofluidics offers advantages over other microfluidics methods, such as low cost, simplified designs, and remote droplet manipulation. These are especially relevant for applications like ...

A unique propagation phenomenon of acoustic waves has been discovered, paving the way for developing advanced communication technologies using acoustic devices. The research, published in Physical ...

Surface acoustic wave (SAW) devices and resonators harness acoustic waves propagating along the surfaces of piezoelectric materials to perform signal filtering, sensing and frequency control. These ...

However, not all innovations are equal and nor do they follow a constant upward trend. Instead, their evolution takes the form of an S-shaped curve that reflects their typical lifecycle from early ...

A team of researchers has created a way to inexpensively manufacture acoustic head simulators. They can help measure the way we take in and process sound – especially in noisy environments like ...

This project is investigating the use of passive acoustic sensors for monitoring agricultural activities in Rwanda. One potentially important use of sound is to detect the presence of birds that may ...

The automotive industry continues to be a hotbed of innovation, with activity driven by, among other things, the safety of pedestrians or cyclists and the growing importance of technologies such as ...

Microplastics (MPs), plastic debris smaller than 5 mm, indirectly harm the environment. They are traditionally collected and removed from water by filtering through meshes, which is inefficient.

Using a standard CMOS process, researchers have combined acoustic MEMS and other technology to create a >10-GHz on-chip resonator function for filters and VCOs. How standard CMOS process can be used ...
