Mutual radiation impedance of circular CMUTs on a cylinder
(IEEE, 2016)
In ultrasound imaging, cross coupling of transducer elements through the medium has significant effect on the frequency response, thus affecting the quality of the ultrasound image. In Side-Looking Intravascular Ultrasound ...
Portable low cost ultrasound imaging system
(IEEE, 2016)
The applications of ultrasound in medicine have been increasing in the last decade either in diagnostics or in treatments. Ultrasound is routinely used in clinical examinations, such as pregnancy exams. On the other hand, ...
A prism-based non-linear optical readout method for MEMS cantilever arrays
(Elsevier, 2016-10-15)
This paper demonstrates the use of a single right-angle prism for the optical readout of micro-electro-mechanical systems (MEMS) cantilever arrays. The non-linear reflectivity arisen from the internal reflection at the ...
Receive-noise analysis of capacitive micromachined ultrasonic transducers
(IEEE, 2016)
This paper presents an analysis of thermal (Johnson) noise received from the radiation medium by otherwise noiseless capacitive micromachined ultrasonic transducer (CMUT) membranes operating in their fundamental resonance ...
Optical fiber array based simultaneous parallel monitoring of resonant cantilever sensors in liquid
(Elsevier, 2016-05-01)
This paper reports a novel method for simultaneous resonance monitoring of MEMS cantilevers using phase based dynamic measurements without any electrical connections to the sensor array. MEMS cantilevers are made of ...
MEMS cantilever sensor array oscillators: Theory and experiments
(Elsevier, 2016-01-01)
This paper demonstrates that an array of cantilever sensors can be operated simultaneously at resonance using a single actuator and a single photodetector. Self-sustained oscillations (SSOs) of cantilevers can be achieved ...
