All-polymer ultrasonic transducer design for an intravascular ultrasonography application
(TUBITAK SCIENTIFIC & TECHNICAL RESEARCH COUNCIL TURKEY, ATATURK BULVARI NO 221, KAVAKLIDERE, ANKARA, 00000, TURKEY, 2019)
Intravascular ultrasonography (IVUS), a medical imaging modality, is used to obtain cross-sectional views of blood vessels from inside. In IVUS, transducers are brought to the proximity of the imaging targets so that ...
Clinical probe utilizing surface enhanced Raman scattering
(A V S AMER INST PHYSICS, STE 1 NO 1, 2 HUNTINGTON QUADRANGLE, MELVILLE, NY 11747-4502 USA, 2014)
Conventional Raman scattering is a well-known technique for detecting and identifying complex molecular samples. In surface enhanced Raman scattering, a nanorough metallic surface close to the sample enormously enhances ...
Analytical design of MEMS variable capacitors based on shaped-finger comb-drives
(SPRINGER HEIDELBERG, 2022)
A variable capacitor is one of the widely used components in radio frequency (RF) circuits. Variable capacitors can benefit from the microelectromechanical systems (MEMS) technology, to be equipped with attractive ...
AlN Piezoelectric Quad-Actuators for 2D Optical Micro Scanning
(TAYLOR & FRANCIS LTD, 2022)
Piezoelectric actuation has been one of the frequent choices for
optical micro scanning. In most of the cases, lead zirconate titanate
(PZT) has been used as the piezoelectric material. However, PZT has
a potential issue ...
Quasi-Static Operation of 2-Axis-Tilt Microscanners with AlN Piezoelectric Quad-Actuators
(IEEE, 2021)
