Currently, the most advanced micromachined microphones on the market are based on a capacitive coupling principle. Capacitive micro-electromechanical-system-based (MEMS) microphones resemble their millimetric counterparts, both in function and in per

The possibility to steer floating cells dispersed in water by means of flexural plate waves (FPWs) generated by a 9 mm $\times9$ mm piezoelectric MEMS transducer has been explored. The MEMS transducer has a squared cavity etched out in a silicon subs

Abstract Chaotic systems, presenting complex and nonreproducible dynamics, may be found in nature, from the interaction between planets to the evolution of weather, but can also be tailored using current technologies for advanced signal processing. H
