The University of Sheffield is a remarkable place to work. Our people are at the heart of everything we do. Their diverse backgrounds, abilities and beliefs make Sheffield a world-class university.

We offer a fantastic range of benefits including a highly competitive annual leave entitlement (with the ability to purchase more), a generous pensions scheme, flexible working opportunities, a commitment to your development and wellbeing, a wide range of retail discounts, and much more. Find out more about our benefits (opens in a new window) and join us to become part of something special.

Overview

We have an exciting, cross-disciplinary role, working as part of a team to develop a novel insect tracking system that could lead to new insights in animal intelligence and have spin-out opportunities. This role develops the vital microbattery power source for these tags. The overall project develops a novel tracking method that expands animal tracking to a huge range of species, which will lead to a revolution in movement ecology.

To enable this we need light-weight microbatteries. You will initially focus on the development of these micropower solutions: building on proof-of-concept work, you will develop production-scalable approaches for sub-10mg lithium microbatteries, with over 150μAh capacity. The battery is likely to have many other applications (with a possible spin-out to allow us to scale production). You will also build on initial work experimenting with thin-film solar as an alternative approach. In the next phase, as well as supporting tag deployment you will develop novel electrically-small antenna (guided by Dr Stephen Henthorn) using extreme meandering and metamaterial-inspired approaches.

You will be working as part of a friendly and supportive, highly cross-disciplinary team including PhDs, RF-engineers, other Research Associate and ecologists, giving you the opportunity to learn new skills and experience and publish in several fields. You will be based in Sheffield but may visit Exeter to support collaborators deploying the system. The wide range of disciplines involved means that you will have a great opportunity to move into several future areas (battery chemistry, machine learning, movement ecology, RF-engineering, electronics etc).

Main duties and responsibilities

• Devise, develop and test fabrication approaches for the construction of microbatteries in a scalable manner (using thin-film polyimide PCB as the substrate), addressing the following questions:
  • How to seal the batteries?
  • Experimenting with various construction approaches - could we laser cut components in place, for example?
  • Could we build the battery directly onto the same PCB as the rest of the tag’s SMDs?
• Test battery capacity, current, longevity, mechanical properties etc.
• Support wider integration into the tag (connections, in-situ charging etc).
• Other related work:
  • Potentially expand microbattery construction methods for other applications (including different geometries and capacities, e.g. though stacking).
  • Integrating and testing small thin-film solar cells into the tag.
  • Support the testing of small antennas for further reductions in tag size.
  • Could the size be reduced further (especially if directly built on circuit PCB).
• Write journal articles and present at conferences the results of this work.
• Carry out other duties, commensurate with the grade and remit of the post
