Characterization and Fatigue of the Converse Piezoelectric Effect in PZT Films for MEMS Applications

Paul Muralt, Ramin Matloub Aghdam, Andrea Mazzalai, Nachiappan Chidambaram, Davide Balma

A measurement setup for the detailed study of the transverse piezoelectric coefficient e(31,f) in the converse (actuator) mode was developed. It allows the assessment of the piezoelectric stress in thin films on silicon cantilevers and provides for a corre ...

Magnetoelastic Clock System for Nanomagnet Logic

Mariagrazia Graziano, Davide Balma

In recent years, magnetic-based technologies, like nanomagnet logic (NML), are gaining increasing interest as possible substitutes of CMOS transistors. The possibility to mix logic and memory in the same device, coupled with a potential low power consumpti ...

Process optimisation of a MEMS based PZT actuated microswitch

Davide Balma

In this work the fabrication of a piezoelectrically actuated microswitch for high current applications is proposed. The device was obtained by assembling two silicon substrates: one containing the signal lines and the other enclosing a silicon nitride (Si3 ...

High Piezoelectric Longitudinal Coefficients in Sol-gel PZT Thin Film Multilayers

Paul Muralt, Antonia Neels, Silviu Cosmin Sandu, Alex Dommann, Andrea Mazzalai, Nachiappan Chidambaram, Davide Balma

A five-layer stack of lead zirconate titanate (PZT) thin films with Pt electrodes was fabricated for potential applications in nanoactuator systems. The 1 mu m thick PZT films were deposited by a sol-gel technique, the platinum electrodes by sputtering. Th ...

Resonant PZT MEMS Scanner for High-Resolution Displays

Paul Muralt, Davide Balma, Sven Holmström

A resonant piezoelectric scanner is developed for high-resolution laser-scanning displays. A novel actuation scheme combines the principle of mechanical amplification with lead zirconate titanate (PZT) thin-film actuation. Sinusoidal actuation with 24 V at ...
