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

Ultrasound imaging has been developed for image-guided radiotherapy for tumor tracking, and the flexible array transducer is a promising tool for this task. It can reduce the user dependence and ...

Monopolar ultrasound pulse holds significant potential for high-resolution imaging and harmonic imaging. Here, we propose to generate a quasi-monopolar ultrasound pulse by superposition of two ...

这一区间的选择并非偶然：当频率低于 40kHz 时，变压器铁芯体积难以缩小，无法满足现代电源的小型化需求;而超过 100kHz 后，反激拓扑中变压器漏感引发的电压尖峰将急剧增加，可能导致开关管的过压损坏。

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.

There is an increasing interest in developing next-generation wearable ultrasound patch systems because of their wide range of applications, such as home healthcare systems and continuous monitoring ...

A new ultrasound for the mouth could help clinicians ‘monitor treatments and diagnose earlier’. The team at the American Chemical Society developed a small, non-invasive ultrasound method capable of ...

A toothbrush-like ultrasound transducer that offers a less invasive screening for gum disease has been developed by a team of researchers from the University of California, La Jolla. As an alternative ...

Discover a new ultrasound tool that could replace painful dental probes, offering a more comfortable and accurate gum assessment.
