In this work, nanometric displacement amplitudes of a Piezoelectric Flextensional Actuator (PFA) designed using the topology optimization technique and operating in its linear range are measured by using a homodyne Michelson ...

Recently, two phase evaluation methods were proposed to measure nanometric displacements by means of digital speckle pattern interferometry when the phase changes introduced by the deformation are in the range [0, π) rad. ...

Piezoelectric flextensional actuator (PFA) devices consist in a technology in development, with increasing number of applications in precision mechanics such as nanotechnology equipments, electronic microscopy instruments, ...

Nanostructured polyelectrolyte complexes (nano PECs) based on biopolymers are an important technological strategy to target drugs to the action and/or absorption site in a more effective way. In this work, computational ...

In this work we introduce an alternating magnetic field generator in a cylindrical nanostructure. This field appears due to the rotation of a magnetic domain wall located at some position, generating a magnetic region that ...

The class of piezoelectric actuators considered in this paper consists of a multi-flexible structure actuated by two or more piezoceramic devices that must generate different output displacements and forces at different ...
