Electronics of the future

Our work is based on materials engineering at the micro/nanoscales and deploy them for a range of applications in electronics, healthcare and environmental monitoring. The work involves three core areas. First, is the investigation of two-dimensional semiconducting materials, understanding fundamentals, engineer defects and deploy them to create field-effect transistors and emulation of synaptic interfaces. Within this theme, our work has also demonstrated the ability to create semiconductor-free transistors by fabricating extremely small gaps between metal electrodes.

Second is based on utilising metal oxide thin films to create chips that can mimic the human brain for storing and recalling past information.  This is based on engineering oxygen vacancy movement via electric fields to create multiple resistance states within a single device.

Third is translating these functionalities onto stretchable platforms and the development of wearable sensors for monitoring of UV radiation, obnoxious gases and biomarkers that indicate onset of disease. This is based on the discovery of a unique transfer process using which brittle high-temperature metal oxides can be transferred onto elastomeric platforms such as Polydimethylsiloxane (PDMS). This allows translating the full-suite of properties that metal oxides have on offer into wearable sensors and devices. We have also developed coatings for smart windows for infrared control using a phase change material.


Sumeet is a Vice-Chancellor’s Fellow and Victoria Fellow in the School of Engineering at RMIT University. His team focuses on engineering small scale materials and deploying them for applications in next-generation electronics, optoelectronics and sensors. Sumeet’s work has been recognised through several awards for innovation and impact which include being named one of the Top 10 Young Innovators in APAC, Victorian Young Achiever for Research Impact and Australia’s most Innovative Engineers.

He has published over 70 peer-reviewed outputs, four patents and edited two books. He co-leads a CRC-P which aims to develop non-invasive biometric sensors for the Australian aged-care facilities. He is active in research translation and working with several industry partners to create end-user products.
