Bachelor or Master Thesis: Miniature scale cooling using shape memory smart materials

 In Germany, refrigeration accounts for 14% of electricity consumption. Cooling on a small scale, as it is required, e.g., in electronic chips, lab-on-chip systems, chemical and biological analysis, is often performed by miniaturization-compatible thermoelectric cooling, which is however rather in-efficient.

The search for energy-efficient, ’green’ alternatives has recently lead to increased interest in solid-state cooling based on caloric effects. Among these, the elastocaloric effect in shape memory alloys exhibits particularly high temperature changes and material-level coefficients of performance (COP) exceeding 80% of the thermodynamic maximum. Shape memory alloys belong to the class of smart materials showing heat absorption, heat generation, actuation and sensing. The goal will be to explore the potential of the elastocaloric effect in these materials for small-scale or ’microcooling’ applications, making use of shape memory films. Although this thesis is targeted at miniature scale cooling, it may also be used for larger scales in parallel architectures.

Your Tasks:

• Characterization of the elastocaloric effect in SMA film materials
• Modelling (Matlab, Simscape) and design
• Prototype development: Fabrication, performance tests, characterization

To carry out the work, the IMT has extensive state-of-the-art equipment (600 m² clean room, rapid prototyping processes such as 3D printing and laser cutting, assembly and joining technology laboratories, various metrological laboratories). Intensive support ensures that the work can be carried out within the given time frame.

Bachelor or Master Thesis: Evaluate flow behavior in von Karman vortex street by magnetic resonance velocimetry

 Oscillating vortices are generated when fluid flows past a bluff body and are known as Von Karman vortex street. The bluff body leads to alternating low-pressure areas, which cause periodic crosswind forces. The crosswind forces can be highly undesirable since they cause vibration, but they can be employed to design vortex flow meters. Therefore, it is very beneficial to evaluate flow behavior in Von Karman vortex street in order to address the adverse effects of vibration as well as to improve the performance of vortex flow meters.

Furthermore, magnetic resonance velocimetry is one the best methods to obtain a 3-dimensional 3-component velocity map due to three main advantages. First, it is a completely noninvasive method. Second, there is no necessity to have optical access to the sample. Finally, one does not need to add any tracing particle to sample to measure the velocity.

Aforementioned reasons led to the idea of evaluating flow behavior in Von Karman vortex street by magnetic resonance velocimetry. The selected applicant is supposed to make the samples based on the design of Von Karman vortex street and perform MRV experiments to assess flow behavior. Having knowledge in fluid mechanics and MRI is a plus, but there will be some training hours especially to get to know how to perform experiments with MRI machine.

Bachelor or Master Thesis: Elastocaloric Cooling with Elastomers

 In Germany, 14 percent of electricity consumption is used for refrigeration. This amount is expected to rise steadily in the future. Innovations in this field can therefore make an important contribution to climate and environmental protection.

The young research field of elastocalorics has the potential to provide efficient and environmentally friendly cooling power. Elastocaloric cooling is based on the reversible release and absorption of heat when specific materials are subjected to mechanical stress or stress-relieved. So far, most frequently the material class of shape memory alloys (SMA) has been used and investigated for its elastocaloric effect. In addition to shape memory alloys, elastomers such as cross-linked natural rubber also exhibit the elastocaloric effect. The elastocaloric effect in elastomers is of special interest for environmentally friendly and low-cost cooling applications.

The focus of this work is on the application of rubber-based films. These have the potential to overcome the various challenges associated with elastocaloric cooling, including large adiabatic temperature changes and exceptional fatigue resistance under dynamic loading. Based on these, a demonstrator of an elastocaloric cooling unit will be designed, fabricated and investigated.

The thesis can be written in German or English.

Tasks:

• Material characterization (dynamic tensile testing, IR thermography, thermal conductivity and heat capacity measurement).
• Simulation of heat transfer (Matlab/Simscape)
• Development, fabrication, commissioning and optimization of a demonstrator

The focus of the work can be tailored to the applicant's interests and competencies. IMT has extensive state-of-the-art equipment to carry out the work (600 m² clean room, rapid prototyping processes such as 3D printing and laser cutting, assembly and joining technology laboratories, various metrological laboratories).

Bachelor or Master Thesis: Feasibility Study „Wearable Ultrasound Detector for Breast Cancer Detection“

 The aim of this work is to propose a first setup for a breast cancer detecting wearable ultrasound detector system (“USCT Bra”) based on the 3D ultrasound Computer Tomography method of KIT. The industrial cooperation partner IcosaMed (CH) is working on the development of a first wearable monitoring device for women’s breasts, in a “smart bra”. This solution will offer a simple monitoring solution for women with genetic breast cancer risk factors or cancer history. These populations represent respectively 0.3% and 3% of all women, or 1.3 million and 13.8 million women in developed countries.

The IPE at KIT developed a prototype for 3D ultrasound tomography (3D USCT) aimed at breast cancer diagnosis and carried out a first clinical study. The current prototype under commissioning is aimed at a larger multicenter study. The IPE also developed imaging algorithms and software as well as methods to optimize a given system layout. The current prototypes are stand-alone systems of the size of a patient bed with a transducer aperture with 34 cm diameter and 2304 ultrasound elements. The patient bed includes motion mechanics and data control and acquisition electronics.

The main challenge of this feasibility study will be to combine the ideas of a wearable USCT bra with the patient bed design of 3D USCT, i.e. to miniaturize the system. In this first step the system layout of the ultrasound transducer aperture in form of a bra will be considered. The feasibility study should result in a proposal for the number, position and needed characteristics (center frequency, bandwidth, and opening angle) of the ultrasound transducers and make a prediction about reachable resolution and contrast of reflectivity imaging.

Work plan:

• Research of state of the art (1 month)
• Simulation and optimization of bra aperture and transducers (3 months)
• Simulation and reconstruction of breast images (1 month)
• Documentation of results (1 month)

Bachelor or Master Thesis: Thermal energy harvesting using a bistable shape memory actuator

 New energy harvesting concepts are currently being developed to convert waste heat into electrical energy. Promising candidates are freely movable film devices of shape memory alloys (SMAs). When brought in contact to a heat source, they generate work due to the shape memory effect, which can be converted into electrical energy. Thus, small temperature differences in the environment can be used to power, e.g., wireless sensor networks for the “Internet of Things“. A sketch of such an energy harvesting device in its two equilibrium positions is shown in the Figure.

This interdisciplinary work focuses on energy generation on a miniature scale covering different fields of materials science, mechanical and electronic engineering. The focus of the work can be adjusted to the interests and competences of the applicant in a direct interview.

Tasks:

• Characterization of material properties (structure, mechanical, thermal, magnetic)
• Modelling, design and simulation (FEM Multiphysics, Lumped Element Modelling)
• Rapid prototyping (Optical lithography, 3D Printing, laser technology)
• Characterization of demonstrator variants (thermo-mechanical, electrical properties)
• Design optimization

Bachelor or Master Thesis: Thermal microactuation using shape memory smart materials for waste heat recovery

 Among the various transducer materials, shape memory alloys (SMAs) offer a number of unique properties including thermoelasticity, superelasticity, actuation at highest work densities up to 107 Jm-3 and self-sensing. SMA actuators make use of temperature-induced martensitic transformation allowing for high actuation force and stroke length. Their characteristic of being a “smart material” becomes particularly advantageous upon miniaturization, as technology constraints pose severe limitations on the number, geometry and size of functional structures.

The goal of the Master Thesis will be to explore the potential of the shape memory effect in a novel out-of-plane actuator design for miniature actuation applications, with emphasis on utilization of low-grade heat as heat source < 200 ℃.

Your Tasks:

• Characterization of SMA material properties (structure, mechanical, thermal)
• Design development based on lumped element modelling (Matlab/Simulink)
• Prototype development including fabrication technology, performance control and characterization

Objectives:

• Design and fabrication of SMA microactuators
• Development of test setup
• Characterization of mechanical and thermal performance
• Evaluation of performance results and design optimization
• Development of control strategy

To carry out the work, the IMT has extensive state-of-the-art equipment (600 m² clean room, rapid prototyping processes such as 3D printing and laser cutting, assembly and joining technology laboratories, various metrological laboratories). Intensive support ensures that the work can be carried out within the given time frame.
