A PhD student in Electronics with focus on self-powered smart bearings

Department of Computer and Electrical Engineering

At the department, education is conducted in the subjects of computer engineering, electronics, electrical engineering and sound production. The research at the department takes place at the research center Sensible Things that Communicate (www.miun.se/stc) and deals with sensor-based systems and services for use within the Internet of Things and artificial intelligence.

Job descriptionIndependent third-cycle studies encompassing research (100%). The research work for this PhD position will be carried out in the Autonomous Sensor Systems group. You will be part of a large European research project on Internet of Things (IoT) devices with long operating lifetime. This will be achieved by developing and integrating energy harvesting solutions into equipment and infrastructure to enhance battery life or replace batteries entirely.

This PhD position focuses on a case of smart bearings. Bearings are often a point of concern in industrial and transport systems, as they are critical components. Degradation and maintenance needs should therefore be detected in good time with the help of monitoring systems. In this project, electromagnetic transducers will be developed and optimized to harvest energy from rotations and to obtain relevant signals about the operation and status of the bearing. This will include the analysis of transducer structures in simulation and experiments, the evaluation of trade-offs between optimisations for harvesting or sensing, signal analysis with machine learning, as well as system integration.

As a PhD student in the Autonomous Sensor Systems group, you will be a vital part of the research group, collaborating with other PhD students, post-docs and senior researchers. Your studies will consist of courses and own research work, developing your competences through theory and experiments. You are expected to bring forward own ideas in the development of your research agenda, and to contribute to the publication and presentation of results. The research group, in turn, will provide a forum for discussion, supervision and assistance during your studies, supporting your research and career development. You will be part of a leading group in the field of low-power sensing systems and be able to exploit the groups large international network.

Entry requirementsGeneral entry requirements include a second-cycle level qualification, or fulfilment of courses comprising at least 240 credits of which at least 60 credits must be at second-cycle level, or the equivalent knowledge gained in some other way in Sweden or abroad. Specific entry requirements include at least 90 credits in the subject of electrical engineering, electronics engineering or computer engineering, or the equivalent knowledge gained in some other way in Sweden or abroad.

Assessment criteriaThe assessment of applications to this PhD position will be based on the applicants’ previous experience (e.g., thesis works, projects, internships, and work experience), the relevance of undergone educational programmes and courses, results of previous studies, and the applicants’ vision for the intended PhD studies.

We see it as an advantage if you enjoy working at the intersection of mechanical and electrical systems, and have previous experience with sensor or transducer utilization, development and/or optimization through simulation and/or experimental work. Previous experience with energy harvesting and/or machine learning is beneficial, but not mandatory. You should have previous experience in programming in, for example, Python, Matlab, or C++.

Personal qualitiesIn addition to your technical competences, your suitability for PhD studies will be evaluated based on your ability to collaborate with others, to work independently, and to communicate clearly.

Employment processProcessing of the appointment will comply with the provisions in Chapter 5 of the Higher Education Ordinance, and will be carried out in accordance with Mid Sweden University’s Employment Procedures

Terms of employmentThe doctoral studentship position corresponds to four years of full-time studies and is expected to lead to a Degree of Doctor. The entry date is 1 September 2023, or as agreed.
