About the position

We are looking for a research fellow within MEMS ultrasonics, focusing on Piezoelectric Micromachined Ultrasound Transducer (PMUT)-based power transfer. 

Are you interested in PMUTs, and want to engage in research with skilled colleagues who share your interests?  Maybe you can become our new colleague at Department of Microsystems at Faculty of Technology, Natural Sciences and Maritime Sciences. The position is available from 01.08.2026 with the latest starting date on 01.01.2027. 

This is an educational position that is primarily intended to give promising researchers the opportunity to develop academically and professionally through organised research training.

It is a condition that the person who accepts the position applies for and is granted admission to the Faculty’s doctoral programme PhD in Technology within three months of starting in the position. 

The doctoral programme includes relevant courses corresponding to approximately six months of study, a thesis based on independent research, active participation in national and international research environments, relevant research dissemination, a trial lecture and public defence of the thesis. Read more about organised research training at USN on our website.

The research fellowship is for a fixed term of three years with pure organised research training.  

Your personnel manager will be head of department Marius Stian Tannum and your supervisor will be Associate Professor Hamed Salmani.  The place of work will be at campus Vestfold. It is a prerequisite that you can be present at, and available to, the academic environment at your workplace during ordinary working hours.

About the doctoral project

The person appointed will be affiliated with the research project “Acoustic power transfer for wireless sensors”, which is led by Professor Einar Halvorsen.

The research project investigates different means to power wireless sensors in structures from acoustic sources. The work package which this position belongs to focuses on miniaturizing acoustic power transfer using piezoelectric microelectromechanical-systems(MEMS) technology. The candidate will use theoretical and numerical methods to investigate how to design miniaturized, acoustically powered nodes and analyze the behaviour of different device concepts.  The most interesting concepts will be further explored experimentally by micromachining and characterization of transducers for transmitting and receiving acoustic power.

The person appointed will be affiliated with the research group Micro- and Nanoelectromechanical Systems (MNEMS).

Duties

• Complete the doctoral programme up to completion of the doctoral degree within the employment period. 
• Conduct high-calibre research within the framework described above.
