The goal of this project was the experimental characterization and modeling of capacitive micromachined ultrasound transducers (cMUTs). The cMUTs being tested are fabricated using layers common to standard commercial CMOS processes. Two designs of micromachined [...]

Shape Memory Alloy and Elastomer Composite MEMS Actuators

Fallon P.D., Gerratt A.P., Kierstead B.P., White R.D., Tufts University, US

Shape memory alloy (SMA) microactuators are under development for use in soft bodied robotics. These actuators take advantage of the shape memory effect of nickel-titanium alloys (nitinol) to deliver high force and large strain in [...]

MEMS Pressure Sensor Array for Aeroacoustic Analysis of the Turbulent Boundary Layer on an Airplane Fuselage

Krause J.S., White R.D., Moeller M.J., Gallman J.M., De Jong R., Tufts University, US

This paper describes a front venting MEMS pressure sensing array, fabricated through the MEMSCAP PolyMUMPS process. The microphone array will be used to analyze the turbulent boundary layer (TBL) of an airplane fuselage in wind [...]
