Abstract Semiconducting effects in zinc oxide nanowires‐based nanogenerators greatly impact their performances. A coupled model integrating piezoelectric and semiconducting properties is developed with a finite element method to better understand the phenomena involved this kind of device made process including chemical bath deposition nanostructures polymer encapsulation. Free carriers surface...

The emerging electro-mechanical impedance technology has high potential for in-situ health monitoring and NDE of structural systems and complex machinery. At first, the fundamental principles of the electro-mechanical impedance method are briefly reviewed and ways for practical implementation are highlighted. The equations of piezo-electric material response are given, and the coupled electro-m...

We report on the development of a metrological multiaxis nanopositioning device, which is operated by the piezo-based inertial method, as a sample stage for scanning probe microscopy. It has long moving range, unlimited in principle, and nanometer ~microradian! resolution. Two operation methods, inertial sliding and inertial walking, can be applied to the stage and the inertial operating method...

Starfish and octopuses control their infinite degreeof-freedom arms with panache—capabilities typical of nature where the distribution of reflex-like intelligence throughout soft muscular networks greatly outperforms anything hard, heavy, and man-made. Dielectric elastomer actuators show great promise for soft artificial muscle networks. One way to make them smart is with piezo-resistive Dielec...

Zinc oxide is one of the most popular materials for acoustoelectronic sensors and vibro-piezo-transducers used in nano-piezo-generators. In present paper, thick piezoelectric ZnO films are fabricated on both sides various substrates using magnetron sputtering technique. It shown that main problem double film deposition difference thermal expansion coefficients substrate materials. The solved by...
