This paper concerns the design and fabrication of new transducer movers dedicated to 3D ultrasound sensors. Our MEMS-based movers were designed using CoventorWare finite element software to maximize the sector and rotation scan angles. These movers are fabricated on silicon wafers using the standard PolyMUMPs process. The design includes both a scanner actuated using four trapezium electrodes and...
We present a novel technique to study the behavior of liquids in microfluidics. An array of capacitive sensors realized in CMOS circuitry is considered to detect the liquid in a channel integrated on top of CMOS chip. A microfluidic packaging procedure is described using a robotic-based fabrication process and the preliminary experimental results are reported. Also, the capacitive simulation results...
Of the 18 module designs in ITER, the US is responsible for three. Each of these modules will be designed to meet requirements established by the ITER international organization (ITER IO). Finite element analysis (FEA) is being utilized to ensure that the module designs are in compliance with the strength requirements established by ITER IO. The strength requirements are defined in terms of maximum...
In this paper, the development of a micro electromechanical scanner incorporating high frequency ultrasound transducer operating at 3.5 MHz is presented. We describe the structure and analysis of a microsystem that can be used as a scanner in based medical imaging system. The scanner consists of a rectangular platform attached to a frame actuated using four trapezium electrodes. The behavior of the...
