Two PhD positions in Micropower-Devices/Systems and Nanomagnetics Group at Tyndall
PhD Fellowship in “Micro-Nano-Magnetics for integrated device applications"
Project: The rapid growth of miniaturized handheld electronic devices & ‘Internet of Things-IoT’ has highlighted the issue of efficient powering and transmission at ultra small scale. Lately, integrated micronano-magnetic devices have become core building blocks of such miniaturized/monolithic powering & transmission devices such as highly miniaturized electromagnetic transducers (magnetic-MEMS), nanooscillators (SHNO/STNO), antenna (Magnonic, NEMS) etc. The focus of the present project will be on modeling, development and characterization of such devices, suitable nano-structured magnetic materials using patterned structures on Si/SOI in a CMOS compatible technique, while identifying & analyzing relevant exchange coupling phenomena in multi-nano-layers of patterned magnetic nanohetero-structures.
Position available: PhD Position: Applications are sought for a four year PhD position with fellowship (€18,500/annum - tax-exempted + Tuition fees (€5,500/annum), will be paid from the project) under supervision of Prof. Saibal Roy in the ‘Micropower Devices & Nanomagnetics’ research group, Tyndall National Institute, University College Cork (UCC), Ireland. The successful applicant will work as part of a multidisciplinary team with a focus on the development of integrated micro-nano-magnetic devices.
The research of this particular position will involve elements of the following;
Review of state of the art (publications in Journals and Patents)

PhD Fellowship in “Nonlinear wideband vibrational energy harvesting using novel MEMS/NEMS electromagnetic/ magnetoelectric transducers for powering wireless sensors for IoT "
Project: The rapid growth in the field of wireless sensor networks aiming the realization of ‘Internet of Things- IoT’ has highlighted the issue of powering wireless sensor nodes perpetually. The requirement of changing batteries places an unwanted additional maintenance and enormous cost burden on such ubiquitous wireless nodes/networks. In certain applications, where environmental vibrations are present, there is the opportunity to harvest the kinetic energy of these vibrations through appropriate design and fabrication of tiny (Micro Electro Mechanical Systems- MEMS / Nano Electro Mechanical Systems- NEMS) transducers and use these to power the wireless sensor nodes. The focus of this PhD project will be on design, modelling and development of vibration based nonlinear wideband electromagnetic / magnetoelectric micropower generators using micro magnets, integrated conducting coils and MEMS/NEMS structures on Silicon. The project will also include development and characterization of nano-structured magnetic materials / multi-nano-layers for device integration, characterization and further validation.
