Proceedings ArticleDOI
Bias optimization of dual ring CMUT arrays for forward looking IVUS applications
TL;DR: In this paper, the authors investigated optimal DC biasing schemes for Tx and Rx elements of identical geometry with separate bias electrodes, and showed that the optimal transmit conditions regarding bias and pulse characteristics do not coincide with the optimal receive bias.
Journal ArticleDOI
A Hybrid Boundary Element Model for Simulation and Optimization of Large Piezoelectric Micromachined Ultrasonic Transducer Arrays
TL;DR: A hybrid boundary element model is proposed for the simulation of large piezoelectric micromachined ultrasonic transducer (PMUT) arrays in immersion, wherein membrane structures are modeled by a surface mesh that is coupled mechanically by mass, stiffness, and damping matrices, and acoustically by a mutual impedance matrix.
Proceedings ArticleDOI
Design of frequency-division multiplexing front-end receiver electronics for CMUT-on-CMOS based intracardiac echocardiography
TL;DR: The design of the CMOS receiver circuit which implements a Frequency Division Multiplexing (FDM) scheme to achieve reduced number of output channels is explored and post layout simulation results from the chip showing the viability of the approach are presented.
Journal ArticleDOI
A grating-assisted resonant-cavity-enhanced optical displacement detection method for micromachined sensors.
TL;DR: Analytical modeling of the structure shows that the etalon significantly improves the detection sensitivity as compared to a regular optical interferometer and the embedded diffraction grating enables integration of optoelectronics in a small volume.
Journal ArticleDOI
Shape evolution of multiple interacting droplets in inkjet deposition
TL;DR: In this paper, an experimentally validated numerical solver based on the combination of the lattice Boltzmann method and the phase-field model was used to study the interface evolution during the material joining process in ink-jet deposition.
