Title: Innovations by Xuanming Lu in Ultrasound Technology
Introduction
Xuanming Lu is an accomplished inventor based in Issaquah, WA (US). He has made significant contributions to the field of ultrasound technology, holding a total of 2 patents. His work focuses on enhancing the performance and efficiency of ultrasound transducer arrays.
Latest Patents
Xuanming Lu's latest patents include a method for forming an ultrasound transducer array and a piezoelectric and CMUT layered ultrasound transducer array. The first patent describes a technique where an ultrasound transducer array is formed using stealth dicing. A laser is employed to create defects within the piezoelectric substrate and along the desired kerf locations. The substrate is then fractured along these defects, and controlled expansion methods, such as thermal expansion, are utilized to achieve the desired kerf width. Spacers are incorporated to maintain this width, and the kerfs are filled to complete the ultrasound transducer array.
The second patent involves a CMUT or other semiconductor-based transducer stacked with a piezoelectric transducer (PZT). This innovative design ensures that the CMUT is sufficiently thin to minimize interference with sound propagation and crosstalk between transmitter elements. The PZT/CMUT layered structure is utilized as a matrix array, featuring a multi-dimensional arrangement of elements. The CMUT array is formed and thinned using semiconductor processing, allowing the PZT to transmit acoustic energy through the thin CMUT while receiving responsive echoes. Integrated electronics within the thin wafer of the CMUT help to limit interconnection issues for the matrix receive array.
