Wideband high-Q nonlinear resonance for MEMS

Clark J.V., Han Y., Abrol A., Zun Z., Auburn University, US

We examine high quality factor (Q) nonlinear wide- bandwidth resonance for microelectromechanical systems (MEMS) by mimicking high nonlinearity in stiffness by force feedback. The Q and bandwidth are usually thought of as being inversely proportional [...]

Micromachined Ultrasound Integrated Circuit

Hajati A., Latev D., Fujifilm Dimatix Inc, US

we present the design and experimental acoustic test data for an ultrasound transducer technology based on a combination of micromachined dome-shaped piezoelectric resonators arranged in a flexible architecture. Our high performance niobium-doped lead zirconate titanate [...]
