PhD Position in RF Characterization of Advanced Materials to Develop Battery-free Wireless Sensing Systems.

About Tyndall
Tyndall National Institute is an international leader in semiconductors, photonics and deep-tech research and innovation. As a leading collaborative European research institute, Tyndall is a key actor and hosting partner in the delivery of the ‘Chips for Europe Initiative’ (EU Chips Act).

Tyndall is Ireland’s leading research and innovation organisation and it is the national focal point for excellence in deep-tech research, development and graduate training at the convergence of nanotechnology, microelectronics, photonics, electronics and AI. Tyndall is recognised as an international research leader in semiconductor, chip and digital technologies, particularly as applied to the fields of Information & Communications, Health & Life Sciences, Agritech & Food Security, Energy and Climate Mitigation, emerging fields such as quantum, and novel computing paradigms.

The Institute’s key objective is to see frontier research activities having a significant impact on economic development and societal challenges in Ireland, Europe and beyond. Central to Tyndall’s mission is delivering economic impact through research excellence in partnership with industry and academia. With an annual turnover of more than €50m, the Institute has a community of over 600 researchers, engineers, support staff, postgraduate students, interns and industry researchers-in-residence.

With significant committed Irish government support, Tyndall will grow to be 1,000 people by 2030, with approximately 750 researchers, including 250 PhD students. A new 17,000 m2 research building is under development adjacent to the Cork headquarters and there are developing plans to expand Tyndall’s existing Dublin research labs and to establish other research sites within Ireland.

Tyndall’s expansion is also supported by recent national and EU funding wins for significant (M€10’s) additional research equipment across a range of areas such as semiconductor processing, microscopy, quantum technologies, heterogeneous integration, ultra-high speed optical communications and RF through THz characterisation.

About the Role
The WSN group within Tyndall is a multi-national transdisciplinary team of researchers developing embedded systems incorporating sensors, energy sources/conversion, communications and edge AI to create new data sets from sensors deployed ubiquitously in and around our working and living environment – Human Centric Systems.

The Wireless Sensor Networks group at the Tyndall National Institute and University College Cork is offering a PhD position in RF Characterization of Advanced Materials (MXene, Laser Induced Copper, …)for use in electromagnetics systems Rectifying-Antenna (Rectenna) design for Energy Harvesting and Wireless Power Transfer. The project has recently been funded by Research Ireland to develop next-generation of wireless sensing systems using advanced nanomaterials and additive manufacturing technologies.

The research will be hosted in the Wireless Sensor Network (WSN) group and involve a strong collaboration with the Nano technology and Materials Group who characterise materials for a wide variety of applications such as the sensing and energy harvesting system that will be developed.

Key Responsibilities and Research Objectives
The GREEN-MONITORING project aims to develop a supply chain monitoring system that does not require batteries, using innovative technology to harvest energy from 4G/5G signals. This approach relies on advanced circuits that efficiently convert low levels of wireless energy into usable power. To develop this battery-free system, the project uses sustainable materials and affordable additive manufacturing techniques like 3D printing and inkjet printing. By focusing on energy harvesting and eco-friendly design, the project supports a greener future and reduces the need for disposable batteries,This involves the simulation and design of electromagnetic antenna and rectifier (Rectennaa) systems, their synthesis and implementation in IoT sensing technology and the test and characterisation of the Energy Harvesting enabled wireless sensing technologies developed.
The PhD project will combine Tyndall’s expertise in electromagnetic design, energy harvesting and materials nanofabrication to develop novel MXene based wireless sensing systems for real world deployment of energy harvesting enabled sensing technologies.

The successful candidate will be part of a team in the WSN group developing electromagnetic simulations, manufacturing recetnna using a variety of deposition techniques and the test and characterisation of the recetenna systems envisaged. These will be integrated in real world IOT sensing systems for deployment as part of the WSN research agenda.

Additional Responsibilities

Activities will include focused research including literature reviews, hypothesis development and identification of novelty associated with the development of peer reviewed publications commensurate with a PhD thesis.
Work with RF experts and researchers in the WSN group and having Collaboration with the Tyndall Materials Nano technology Group
Engagement in the wider Micro Nano Systems Centre
The candidate will be expected to write scientific publications associated with their work and travel to international conferences, workshops, industry and project meetings.
Participate in Education and Public Engagement activities.
Ensure compliance with Tyndall's Quality Management, and Health and Safety standards.
Perform additional duties as required within the scope of the post.
