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, ...

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 ...

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.

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 ...

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

Biosensors consist of three parts: a component that recognizes the analyte and produces a signal, a signal transducer, and a reader device.
