A micromachined acoustic transducer comprising a parylene diaphragm piezoelectric transducer. The parylene diaphragm has far lower stiffness than the silicon nitride. The method for fabricating the parylene diaphragm acoustic transducer utilizes a prestructured disphragm layer utilizing silicon nitride which is compatible with high temperature semiconductor process. A silicon nitride layer is patterned and partially removed after forming the parylene diaphragm layer in order to enhance the structural qualities of the parylene diaphragm. The diaphragm may be flat or dome-shaped.

A DNA probe synthesis system may include a target holder for holding a target chip, an ejector array chip, a wash and dry station, and conveyance means for moving the target holder and the chip between the ejector array chip and the wash and dry station. The ejector array chip may include ejectors, reservoirs for containing DNA bases, and microchannels all on the same substrate. The ejectors may be Self Focusing Acoustic Transducers (SFATs).

A MEMS silicon inertial sensor formed of a mass that is supported and constrained to vibrate in only specified ways. The sensors can be separately optimized from the support, to adjust the sensitivity separate from the bandwidth. The sensor can sense three dimensionally, or can only sense in a single plane.

A micromachined sensor for measuring vascular parameters, such as fluid shear stress, includes a substrate having a front-side surface, and a backside surface opposite the front-side surface. The sensor includes a diaphragm overlying a cavity etched within the substrate, and a heat sensing element disposed on the front-side surface of the substrate and on top of the cavity and the diaphragm. The heat sensing element is electrically couplable to electrode leads formed on the backside surface of the substrate. The sensor includes an electronic system connected to the backside surface and configured to measure a change in heat convection from the sensing element to surrounding fluid when the sensing element is heated by applying an electric current thereto, and further configured to derive from the change in heat convection vascular parameters such as the shear stress of fluid flowing past the sensing element.

A MEMS silicon inertial sensor formed of a mass that is supported and constrained to vibrate in only specified ways. The sensors can be separately optimized from the support, to adjust the sensitivity separate from the bandwidth. The sensor can sense three dimensionally, or can only sense in a single plane. Vibration cancellation may be provided.
