| Ultrasound helmets are typically used to focus ultrasound on specific regions of the brain to treat tremors. To date, most ultrasound helmets that have been developed are bulky and rigid, have suboptimal resolution, and produce considerable heat. Ultrasound arrays on flexible sheets offer an exciting new direction, but their application has so far been limited to monitoring. Importantly, no current systems are designed for manipulating microrobots within a 3D vasculature. - Biomechanical Engineering, Biosensor Technologies, Control Engineering, Electrical and Electronic Engineering, Flexible Manufacturing Systems, Mechanical Engineering

| Our project aims to enhance the ultrasound-assisted bioprinting process using real-time feedback and image processing. We have developed a transparent nozzle equipped with multiple cameras for real-time monitoring. The next steps involve integrating advanced image processing techniques, such as template matching, and implementing a feedback system to optimize the printing process. The system will be fully automated, featuring a function generator for wave creation and cooling elements. By analyzing the printing process and acoustic cell patterning with computer vision and leveraging real-time sensor feedback, we aim to dynamically optimize parameters such as frequency and amplitude for accurate and consistent pattern formation, crucial for bio applications. - Artificial Intelligence and Signal and Image Processing, Behavioural and Cognitive Sciences, Computation Theory and Mathematics, Computer Software, Engineering and Technology, Information Systems, Medical and Health Sciences

| Our project aims to develop a Python-based software to automate the generation of G-code for 5D printing with a robotic arm, emphasizing slicing along stress curves. The program will interpret Standard Triangle Language (STL) files and integrate user-defined stress parameters to perform stress point analysis. This analysis will inform the slicing paths, optimizing material distribution and enhancing structural integrity. The software will also feature a graphical user interface (GUI) for visualizing parameters, including acoustic pattern analysis. Additionally, it will accommodate the robotic arm's restrictive movements to ensure precise path planning and execution. An integrated feedback mechanism will automate the printing process, improving control and efficiency. - Artificial Intelligence and Signal and Image Processing, Behavioural and Cognitive Sciences, Computer Software, Engineering and Technology, Medical and Health Sciences

| This project aims to develop an integrated control system for a robotic arm-based bioprinter, focusing on enhancing precision and reliability in tissue engineering. The system will control various sensors and actuators, including temperature, humidity, gas sensors, UV lights, pneumatic pumps, HEPA filters, and heating and cooling chambers. Specifically, the control system will ensure environmental conditions are optimal for bioink viability and structural integrity during the printing process. The robotic arm and end effectors will be calibrated to achieve a printing resolution of 200 microns. This initiative will rigorously test the integrated controls to confirm their efficacy in maintaining precise operational parameters, thereby advancing bioprinting technology. - Communications Technologies, Computer Hardware, Electrical and Electronic Engineering, Information, Computing and Communication Sciences, Interdisciplinary Engineering, Manufacturing Engineering, Materials Engineering, Mechanical and Industrial Engineering

| In this thesis, we aim to harness the latest advancements in 3D bioprinting of tissue constructs for drug screening applications. Our focus is on evaluating drug efficacy in custom-built bioprinted tissue constructs, and comparing these with microfluidics, organoids, and spheroid-based drug screening methods. By integrating state-of-the-art bioprinting technologies and novel bioinks, this project aims to create biomimetic tissues that can better mimic human tissue thus significantly enhancing drug screening processes. The research will involve the design of drug screening constructs, the testing of various drugs, and the analysis and comparison to traditional methods. Furthermore, we will explore possibilities to improve the construct design to produce more human-mimetic tissues, thereby enhancing human relevance and optimizing outputs. This will offer a more accurate and efficient platform for pharmacological testing and toxicity analysis. - Biology, Medical and Health Sciences
