University of Portsmouth (UoP) is placed among the top 100 “Universities under 50” in the world. To mitigate its carbon footprint, UoP recently shows its interest to install energy-efficient LED lighting and daylight sensors in the buildings.
Nowadays, the Internet on Things (IoT) is employed to enhance the performance of the energy sector. Almost all sections of the energy sector including generation, transmission, distribution, and demand use a large number of wireless sensors and communication technologies. The new generation of MEMS sensors, low-power VLSI, and CMOS is characterised by extremely low power consumption. Although high energy density lithium-ion batteries can now be employed in the majority of electrical devices, in some applications, their replacement can be a big challenge. For example, the replacement of a battery of proximity or humidity sensor in the nacelle of thousands of offshore wind turbine generators is a very costly and time-consuming process. To tackle the difficulties of replacement/ recharging of the batteries, the extremely low power wireless sensors can be energized by converting the available environmental energy to electricity through energy harvesters. This conversion can be from solar light, vibration, or heat to electricity. Therefore, high-quality energy harvesters play a significant role to provide self-powered monitoring system.
The aim of this PhD research project is the development of a self-powered monitoring system that is suitable for the energy sector. The researcher will concentrate on developing of vibration-based energy harvester to energize the low power sensors (e.g., temperature, humidity, light, etc.). Control of energy consumption of a building (i.e. lighting, heating, cooling, and air conditioning) by the developed self-powered monitoring system will be utilised as the case study for this project. Applicants should have an interest in harvester and low-power sensors as well as detailed knowledge of electronics, manufacturing, and smart materials (e.g. magnetostrictive, etc.).
You'll need a good first degree from an internationally recognised university (minimum upper second class or equivalent, depending on your chosen course) or a Master’s degree in an appropriate subject. In exceptional cases, we may consider equivalent professional experience and/or qualifications. English language proficiency at a minimum of IELTS band 6.5 with no component score below 6.0.
You should have good knowledge of mechatronics, nonlinear vibration analysis, energy harvesting and low-power sensing electronics.
