Micro/Nano Fabrication of Spatial Parallel Manipulators for the Development of Active Nanobots.

This project concerns the development and fabrication of active parallel manipulators in a micro/nano scale.

Parallel mechanisms are intrinsically suitable for their micro/nano fabrication, since the actuators are typically fixed on the base, and their high precision allows them to manipulate matter in a reduced workspace. Given their high stiffness they could be applied for machining, placing and orientating objects in the creation of micro/nano machines.

Structural health monitoring via Microelectromechanical Technology.

Looking for greater revenue, the power output of wind turbines has increased several times over the last few years. This in turn has driven a proportional increase in their physical size, raising tremendous challenges in their structural design and monitoring of structural integrity. The development of embedded sensors within the material during manufacturing of wind turbines, in tandem with advanced data analysis and control systems has the potential of providing a passive tool for estimating the remaining structural life and/or triggering actions for optimizing the power output, all in real-time. To be adopted enthusiastically by industry and the engineering community, such a system needs to be reliable, cost-effective and selfpowered. New technologies in the field of micro-electromechanical sensors (MEMS) have the potential to meet such needs in the short term.

Graphene nanosheetbased micropatterns as electrical conducting thin films.

The aim of this experimental work is to synthesize conductive graphene nanosheetbased thin flms on common cm2-area substrates using simple and low-cost methods. The resulting samples should be compatible with well establish lithography processes in order to micro- and nanopattern the as-prepared films in arbitrary geometries and sizes. This deposition method may be employed in large scale industrial production of graphene.

Studying graphene using quantum walks.

The main objective of this project is to promote cross-fertilisation between the fields of quantum computing and graphene, by exploring how the physical and algorithmic properties of quantum walks can be used to model and predict graphene behavior under several conditions.

Concretely, our proposal consists of the following activities: expressing graphene behavior as quantum walk-based algorithms and Multi-particle quantum walks to analyze graphene properties.

PhD Student Science of Engineering arevalobarb@gmail.com Micro-engineering research with thermal energy applications: Novel exchanger design for enhanced heat transfer.

The research project involves optimizing the generator of an absorption refrigeration cycle within the context of low-grade heat sources (e.g. solar energy). My approach to the problem will be experimental both at a lab bench scale as well as in a pilot plant. The former will test new heat exchanger designs and will obtain fundamental relationships for Nusselt number, and the latter will scale up our designs and test the accuracy of our correlations for heat transfer coefficient.

Recent literature shows there is the opportunity to achieve augmented heat transfer through heat exchanger design at the microscale. We are interested in finding a partner with manufacturing capabilities at this scale and with experience in the field of heat transfer.

PhD Student Science of Engineering rafaelmendoza@ingenieros.com Assistive Active Ankle Orthosis for stroke patients.

In this project, the design and construction of an Active Ankle joint support is described. The orthosis has pressure sensors and adjust braces to be attached to the patient´s lower limb. It is named active due to its electronic actuator mounted in it. This actuator will generate the dorsi and plantarflexion movements of the joint in the swing phase in order to reach the next step and the correct orientation with respect to ground and patient´s posture.

The construction will use the advanced manufacturing techniques of Micro and Nano scale creating a light but resistant structures with specific stiffness coefficient for each patient.
