TL;DR: In this article, a resonant piezoelectric scanner is developed for high-resolution laser-scanning displays, which combines the principle of mechanical amplification with lead zirconate titanate (PZT) thin-film actuation.

TL;DR: A measurement setup for the detailed study of the transverse piezoelectric coefficient in the converse (actuator) mode was developed in this paper, which allows the assessment of the stress in thin films on silicon cantilevers and provides a correlation of this stress with large and small signal responses to ferroelectric polarization and dielectric response, both as a function of slowly sweeping electric field.

TL;DR: This paper proposes an innovative voltage-controlled magnetoelastic clock system aware of the technological constraints risen by modern fabrication processes, and shows how circuits can be fabricated taking into account technological limitations, and evaluates the performance of the proposed system.

TL;DR: The best FOM of the IDE structures was 20% superior to that of the PPE structures while also having a voltage response that was ten times higher (12.9 mV/μ strain) and the ferroelectric loops showed a higher saturation polarization, a higher coercive field, and less back-switching for the IDE case.

TL;DR: In this paper, a high frequency resonant torsional microscanner actuated with thin film PZT is modeled, fabricated, and characterized, which provides significant power and size advantages compared to electromagnetically and electrostatically actuated scanners.
