Wide bandwidth for an air-coupled piezoelectric micromachined transducer (PMUT) is important to achieve short pulse transmission and reception in pulse-echo imaging with high axial resolution. Here, ...

Multifunctional Injectable Microspheres Containing “Naturally-Derived” Photothermal Transducer for Synergistic Physical and Chemical Treating of Acute Osteomyelitis through Sequential Immunomodulation ...

In this paper, we propose a novel piezoelectric micromachined ultrasonic transducer (PMUT) for airborne object detection, which provides high sensitivity compared to the conventional round-shaped PMUT ...
