Project Description

RF/microwave components are essential for telecommunications and radar systems. With on-going development of 5G mobile networks and new generations of satellite platforms, which are the backbone of many emerging applications such as Internet-of-Things (IoT) and Internet-of-Space (IoS), metal 3D printing or additive manufacturing has recently been seen as an enabling technology for future RF/microwave components to meet stringent requirements for system applications. 

Additive manufacturing (AM) is revolutionising how RF/microwave components are designed and manufactured. This all presents a great opportunity and potentially large market of using and commercializing metal 3D printing technology in this field. This industrially collaborative PhD will provide students with the opportunity to interact with researchers and developers from both academic and industry sectors. It is expected that the candidate will work on industry inspired problems and challenges. The project will involve electromagnetic simulation and design of metal 3D RF/microwave components, prototype hardware manufacturing and experimental demonstration. 

The project industrial partner Renishaw is one of the world’s leading engineering and scientific technology companies, with expertise in precision measurement and healthcare. The company supplies products and services used in applications as diverse as jet engine and wind turbine manufacture, through to dentistry and brain surgery. It is also a world leader in the field of additive manufacturing (also referred to as metal 3D printing), where it is the only UK business that designs and makes industrial machines which ‘print’ parts from metal powder. For this project, the company will also offer Additive Manufacturing of prototype on their machines; their commitment of appropriate human resource and use of their ancillary equipment to support research; and a member of staff to be an industrial supervisor and liaison.This project will further strengthen the Strategic Alliance between Renishaw and Heriot-Watt.

Space is key asset for Europe. Europe’s citizens enjoy the benefits, from jobs and economic growth, to public services, efficient communications and security. To respond to global challenges, Europe must continue to have a prominent role in space at a time when other world powers are rapidly developing their space capabilities. Since satellite payload RF components and systems are essential for delivering mission objectives and supporting ground equipment and telecommunication systems, new technologies and techniques are required to respond to emerging satellite applications and technology challenges. To this end, TESLA Innovative Training Network (ITN), a consortium of 8 academic universities and 11 industrial partners, will train 15 PhD students, i.e. Early Stage Researcher (ESR) fellows, in a vibrant, multidisciplinary training-through-research environment uniquely equipped to develop the Advanced Technologies for future European Satellite Applications. The TESLA ESR fellows will pursue PhD in collaborating with senior staff in academic and industrial sectors to conduct top-notch research into new and enabling technologies for satellite flexible payloads, big constellation systems and Internet of Space, satellite high-speed communications and remote sensing, as well as large satellite platforms.

Electromagnetic sensors for wearable healthcare applications

 

Dimitris St

Wearable electronics technology for healthcare management, personal safety, and consumer products enhancement has the potential to transform our everyday life and improve the quality of living of healthcare patients and athletes. Non-invasive healthcare monitoring of body signal bio-parameters – such as movements, respiration, and temperature – without physical intervention or interaction with the patient is particularly of interest in this project. To date, the widespread adoption of many body wearables is limited due to intrinsic limitations mainly related to the flexible/rigid interface: complex wiring, mechanical/electrical reliability, presence of rigid and bulky batteries and charging circuits, washability. Seamless integration is key for user convenience that will ultimately lead to adoption of the technology in everyday applications.  This PhD research project envisages developing a wireless body sensor reader that can detect and estimate human body signals through a passive radio-frequency interrogation process and will be integrated with a sensing antenna. It is expected that this PhD research project will change the conventional approach to wearable healthcare electronics, ultimately leading to novel RF circuit architectures that take advantage of modern System-on-a-Package and System-on-a-Chip technology developments, and it may be a key enabler in lowering healthcare costs, particularly for the elderly.

Eligibility: DTP (UK nationals, or EU citizens who lived in the UK for the past 3 years)

Title: Energy harvesting and wireless power transfer for RFID and wireless sensors: from circuit optimization and signal design to ambient RF backscattering 

Abstract: Backscatter communication and RFID technology provides a foundation, an enabling technology towards the realization of ‘zero-power’ wireless sensors and implementing the Internet-of-Things (IoT) and machine-to-machine (M2M) communication. Interest in RFID technology is further enhanced by its fundamental capability for wireless powering of devices, allowing for battery-less operation. The presentation begins with an overview of ambient energy availability and energy harvesting technology challenges for low power circuits and sensors. Design challenges and novel technologies and materials, such as paper, textiles, and inkjet/3D printing are highlighted. Special focus is placed on electromagnetic energy transfer and harvesting for range maximization of passive RFID systems. Rectenna design and optimization under different operating conditions and in different operating frequencies from HF to millimeter waves is addressed. Multiple technology harvesters leading to the development of energy harvesting assisted RFIDs are discussed. Low profile and conformal solar antennas and solar–electromagnetic harvesters including examples implemented on paper and textile substrates are presented. The integration of an antenna with a thermo-electric generator is demonstrated. Waveform optimization in wireless power transfer is addressed, and the ability to improve the RF-DC power conversion efficiency of electromagnetic energy harvesting devices by tailoring the characteristics of the transmitted signals is discussed. The last part of the talk presents application examples including RFIDs and wireless sensors powered from solar and electromagnetic energy harvesting, millimeter wave back-scattering, solar energy harvesting for RFID tags and sensors based on ambient RF signal backscattering.

Title: Time Reversal Techniques by retrodirective antenna arrays for Wireless Power Transfer 

Abstract: Retrodirective antenna arrays have certain capabilities that can offer some very interesting advantages for wireless power transfer. This includes real-time, automatic target tracking by time reversal and re-radiation of RF power to a specific direction away from the array, and without previous knowledge of the original target location. The workshop will investigate these concepts in the frequency and time domains while also considering practical examples such as the charging of a mobile unit in the far-field using efficient antennas and high-power microwave circuit technologies.
