Computational fluid dynamic modelling for arterial diseases assessment
(Auckland University of Technology, 2012)One of the leading causes of death is cardiovascular disease, being 30% of all deaths worldwide and 40% of those in New Zealand. In other words, every 90 minutes a New Zealander dies due to cardiovascular disease. ... -
Computer Assisted Cardiac Auscultation: Probabilistic Modelling and Psychoacoustic Feature Extraction for Heart Sound Descriptions
(Auckland University of Technology, 2020)Physicians have been using stethoscopes for over 200 years to listen to the sound produced by the heart, but the diagnostic accuracy of this practice has been called into question by studies that have found the clinical ... -
Development and Evaluation of Dry-Contact Electroencephalography (EEG) Sensors
(Auckland University of Technology, 2020)The driving force behind ongoing advancements in dry-contact electroencephalography (EEG) sensor development, is the user-comfort, reduced set-up time and sustained period of use that can potentially be exhibited in wearable ... -
Development of a Cardiovascular Simulator Incorporating a Phantom Simulation of the Arterial System
(Auckland University of Technology, 2021)A mock circulatory loop was constructed to test a new blood pressure device under development. The loop was intended to replicate a range of cardiac conditions with the implementation of an artificial arterial tree. An ... -
Development of an Upper Arm Phantom for BP Measurement
(Auckland University of Technology, 2021)Cardiovascular diseases, such as hypertension, is one of the most commonly occurring afflictions throughout the world. Blood pressure (BP) measurement is critical in the diagnostic analysis of cardiovascular health. The ... -
Development of textile sensors to measure anthropometric and pressure information on children's feet
(Auckland University of Technology, 2019)Bobux is a manufacturer of children’s shoes and approached Auckland University of Technology (AUT) to help solve the pain points that their customers and clinicians have through implement new technology within their products. ... -
Effect of Vibration Imposition on Aortic Muscle Tissue : An Explorative Study
(Auckland University of Technology, 2017)Aorta, the main artery of the human body has a pipe like structure and is tasked with carrying and distributing the oxygenated blood to the various parts of the human body. Development of small kink or obstruction, clinically ... -
Elimination of Skin-stretch Induced Motion Artefacts From Electrocardiogram Signals
(Auckland University of Technology, 2017)Electrocardiography (ECG) is widely used in clinical practice, for example to diagnose coronary artery disease or the cause of chest pain during a stress test, while the patient is running on a treadmill. Ambulatory ECG ... -
Estimating the Normal and Reference aortic Pulse Wave Velocity for the New Zealand Population: Improving Stroke and Cardiovascular Risk Prediction
(Auckland University of Technology, 2020)Arterial stiffness is expressed as the reduced capability of physiological expansion and contraction of arteries during changes in blood pressure (BP). It is measured as carotid-femoral pulse wave velocity (cf-PWV) and is ... -
Feasibility Study of a Novel Electrospinning System with Uniform & Non-uniform Electric Fields
(Auckland University of Technology, 2019)Nanofibres are fibres that are 1000 times thinner than a human hair, they are a versatile form of material made from various polymers. They inherit the properties of the base material while also yielding the properties ... -
An investigation into ambulatory blood pressure measurement
(Auckland University of Technology, 2012)Hypertension is one of the most common cardiovascular diseases threatening people's health worldwide. Although, hypertension itself is rarely an acute problem, it increases the risk of cardiovascular events and kidney ... -
An investigation into the acoustic response of the arteries
(Auckland University of Technology, 2007)In hypertension, aging and certain types of arterial disease, central elastic arteries become stiffer and hence the central pulse pressure is augmented due to the increase in pulse wave velocity (PWV) and the early return ... -
Leak Detection for Waterproof Enclosures using Schlieren Optics
(Auckland University of Technology, 2018)In the search for a method of detecting leak location without danger of damaging the product tested or harming the user, Navico approached Auckland University of Technology (AUT) with the proposition of developing a visual ... -
Multi-frequency Bioimpedance Variations in a Simulated Human Forearm
(Auckland University of Technology, 2017)Bioimpedance analysis (BIA) is a popular technique used in the monitoring of various physiological parameters like arterial oscillation, blood volume flow rate and cardiac output. BIA is based on measuring the impedance ... -
Non-invasive blood pressure measurement algorithm for all age groups
(Auckland University of Technology, 2012)The oscillometric method is the most common technique used in commercial non-invasive blood pressure monitoring. In this technique, devices record the pressure oscillations in the cuff as the cuff pressure decreases from ... -
A Novel Approach for Cuff-less and Continuous Blood Pressure Monitoring Using Deep Learning Networks
(Auckland University of Technology, 2021)Blood pressure (BP) is one of the most important and meaningful vital signs of the human body that can be assessed as a critical risk factor for severe health conditions, especially cardiovascular diseases (CVD) and ... -
Quality-focused Design of Medical IoT Quality Management Systems
(Auckland University of Technology, 2021)Risk management of medical equipment before it is put into service is essential to reduce the risk of medical devices failing. Manufacturers of medical devices are required to minimize the risks associated with the use of ... -
A Study on the Response of Human Phantom Aorta to Externally Imposed Oscillations
