A spacecraft's sample return capsule was detected entering the Earth's atmosphere using acoustic sensors by a team of scientists from the Los Alamos National Laboratory and Colorado State University.

Hence, this approach can be, e.g., used for neuromorphic acoustic sensing, while keeping the geometry of this MEMS sensor as simple as possible.

This study examines the impact of gas and liquid media on the detection characteristics of the sensor diaphragm and proposes using an acoustic impedance matching medium together with a vibrational ...
