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 ...

By using piezoelectric actuators coupled to the tool-holder, one can choose to use different passive and active controls, generating a more versatile tool to control machining vibration. However, one ...

Vibration energy harvesting with piezoelectric materials is of practical interest because of the demand for wireless sensing devices and low-power portable electronics without external power supply.

In order to obtain an ultrasonic transducer (UT) with ultra-broad bandwidth (BW), a multilayer stairstep piezoelectric structure (MSPS) is designed and fabricated. Based on the theoretical computation ...
