On chip energy storage

“Phenomenal Cosmic Powers, Itty Bitty Living space”

At Swistor we are a young start-up developing micro-supercapacitors. Energy storage is nowadays one of the major bottleneck for sustainable technological development. Supercapacitors combine the high-energy storage capability of batteries with the high-power delivery capability of capacitors. At the same time, they have a longer cycling lifetime and use more abundant and sustainable components than lithium ion batteries, turning them into a very attractive competitor for the next generation of energy storage devices.    

The goal of this project is to develop a coating layer that can enhance the energy storage of our carbon-based supercapacitors. By adding a pseudocapacitive coating, usually a transition metal or conductive polymer, the energy storage capability of the supercapacitor can be further extended with minimum effect in the area foot print of the device.

We are looking for a student eager to combine microfabrication, electrochemistry, material science and electronics to contribute to the development of a high-performance supercapacitor that has the potential to revolutionize the way we charge our electronic devices in the future.

Project requirements: Broad interest in electrochemistry, electronic devices and microelectronics/microfabrication knowledge.

Main tasks: Create a pseudocapacitor coating process for supercapacitor microstructures.

Starting date:  A soon as possible

Recommended type of project:  Master project, internship.

Work breakdown:  10% theory, 60% fabrication, 30% characterization.

Past Projects

Master project: Development of a biosensor for troponin detection

Biosensors have shown huge growth in the last years. Current trends are focused on the miniaturization of devices leading to a growing demand for robust, affordable point of care-based technologies that are able to compete with bulkier instruments. The sensitivity and specificity of a biosensor are directly related to the activity of the immobilized molecules and the accessibility of the specific targets. Therefore, surface functionalization chemistry is a key step in the development of the biosensors which should ensure a good surface coverage, proper accessibility of the target to the immobilized biolayer, low non-specific binding, and good reproducibility and robustness. Troponins are protein complexes that modulate the contraction and relaxation of striated muscle and it is considered to be an important marker in the diagnosis of acute coronary syndrome.  In this project a wearable FET biosensor used to detect cardiac troponin for early cardiac disease diagnostic and monitoring will be developed by exploring different surface functionalization chemistries in order to graft molecular probes while preserving their electronic properties.

Thesis abstract

The main objective of the proposed master project is the development of a biosensor for on-site and real-time quantitative analysis of troponin. Surface functionalization chemistries to proper access this protein of interest will be explored over the time course of this master project.

Keywords: troponin, FET, biosensing, surface functionalization


We seek a motivated and ambitious master student to work both independently and as part of a team in an interdisciplinary environment, that is, the Nanoelectronic Devices Laboratory (NANOLAB) group. The NANOLAB, led by Prof. Mihai Adrian Ionescu, has an outstanding reputation of research excellence, state of the art research facility in nanotechnology for health and well-being biosensors. NANOLAB is working on various subjects in the field of silicon micro/nano-electronics with special emphasis on the technology, design and characterization of nanoscale solid-state devices, FET-based biosensors, negative capacitance FET, RF devices, 2D-2D Tunnel FET. The group is very multidisciplinary, and comprises researchers from different scientific backgrounds such as chemists, engineers, and biologists. The focus of the group’s research is exploring new materials, novel fabrication techniques, and novel device concepts for future nanoelectronic systems.
