DOI: 10.1016/j.cryogenics.2017.08.009

Abstract: Abstract Acoustic power at the cold end of regenerator is the measure of gross cooling capacity for a pulse tube cryocooler (PTC), which cannot be measured directly. Conventionally, the acoustic power can only be derived… read more here.

DOI: 10.1088/1361-6439/ab257f

Abstract: Implantable medical devices (IMDs) can be powered wirelessly using acoustics with no need for a battery. In an acoustic power transfer system, which consists of a transmitter, medium, and a receiver, the power that the… read more here.

DOI: 10.1088/1674-1056/26/5/054302

Abstract: As an effective therapeutic modality, high-intensity focused ultrasound (HIFU) can destroy tumour tissues by thermocoagulation with less metastasis, but it is still limited by inaccurate non-invasive temperature monitoring and efficacy evaluation. A model of electrical… read more here.
