In this paper, we present the use of reverse-engineering like techniques to analyse the proposal of a Dual-System Unmanned Aerial Vehicle. Such vehicles are capable of performing vertical flight with the use of a multi-rotor system and then transitio

A hybrid unmanned autonomous vehicle (UAV) combines the high-speed cruise capability of a fixed-wing airplane, with the hovering flight, vertical take-off and landing capabilities of a helicopter. The change between both flight modes refers to as a t

The crystallization of lead zirconate titanate (PZT) thin films was evaluated on two different platinum-coated Si substrates. One substrate consisted of a Pt coating on a Ti adhesion layer, whereas the other consisted of a Pt coating on a TiO2 adhesi

Multilayer actuators (MLAs) offer an increase of force per unit area, a reduction in power consumption, and a reduction in required driving voltages compared with singlelayer actuators. For example, switching from a single 0.5- or 1.0-μm layer of PZ
