Small is Beautiful!

Master thesis project: students applied and experimental physics

Nanostructured materials have given an impetus to modern technology producing systems of smaller dimensions. However the electromechanical performance is size-dependent and leads to various unexpected properties. This can be exemplified by the increasing strength of materials upon decreasing size. In contrast to mechanical properties, for actuating-functional properties of nanostructured foams the situation is less clear. The reason is that besides the microstructure also toplogy plays a predominant role.

Objectives
This project is aimed at investigating the influence of a controlled topology on the actuating properties of these nanoporous metal system.Actuator materials are able to generate mechanical energy through the conversion of electrical, chemical or magnetic energy . They find application in a wide variety of fields, such as robotics, optical communication and in nano-microelectromechanical (NEMS/MEMS) devices. Actuators are also used in the field of artificial muscles and damaged hearts and robots. At present ferroelectric ceramics are commonly used as actuators, but they require rather high voltages (~100 V). Very recently the quest for low-voltage actuators has led to a new class of materials based on nano-structured foams. Nevertheless, the systems studied so far involve rather uncontrolled morphologies and topologies. The objective of this project is to elevate these drawbacks.
