Mission
Current work
The Milli-Tech proposal aims at a novel technology platform serving both computation and sensing: electronic switch architectures, called steep slope switches, exploiting new device physics and concepts in emerging 2D materials to achieve operation at voltages below 100 millivolts. The project develops a technological platform called ‘millivolt technology' focusing on low power digital and sensing/analog electronic functions exploiting steep slopes, with the goal of lowering the energy per useful function (computed and sensed bit of information) by a factor of 100x.
Such ultra-low operation voltage will contribute to solving major challenges of nanoelectronics such as power issues and it will enable energy efficient super-sensitive sensors for Internet-of-Everything (IoE). Milli-Tech includes fundamental research on new solid-state steep slope device concepts: heterostructure tunnel FETs in 2D Transition-Metal-Dichalcogenides (TMD), 2D Van der Waals super-lattice energy filter switch and hybrid architectures combining two switching principles: band-to-band-tunneling and metal-insulator-transition or negative capacitance in VO2, used as additive technology boosters.
DIGIPREDICT FET Proactive Project (https://ec.europa.eu/newsroom/horizon2020/items/699059)
- DIGIPREDICT proposes the first of its kind digital twin to predict the progression of disease and the need for early intervention in infectious and cardiovascular diseases. A digital twin is a digital representation of an object or process from the real world in the digital world & and more specifically for the case of DIGIPREDICT & of a patient. The project combines the latest advances in digital biomarkers, organ-on-chip (OoC) and artificial intelligence at the edge, and aims to build a new interdisciplinary community in Europe focused on digital twins.
The developed system will provide medical doctors with a unique digital tool for early prediction of potential serious complications in COVID-19 patients. Beyond COVID-19, the system promises to also improve the prevention, diagnosis, monitoring and treatment of cardiovascular disease and detect the potential onset of inflammatory disease.
This multi- and cross-disciplinary project will combine scientific excellence with engineering know-how, and leverage the expertise of doctors, biologists, electrical engineers, computer scientists, signal-processing engineers and social scientists from across Europe .
SINERGIA NEMO Project - The NeMO (neuromimetic metal-oxide memristors) Sinergia project aims to develop fundamental understanding, optimized materials and novel device architectures for the engineering of highly tunable metal-oxide neuromimetic memristors. Mimicking biological neurons, the devices that we will develop will operate in voltage (100 to 200mV peak-to-peak) and frequency (0.1KHz to 1 MHz) ranges that will make them 100x more energy efficient than today's equivalent CMOS-based hardware. They will therefore enable implementation of highly energy efficient neuro-mimetic computational hardware for next generation information technologies.
This ambitious goal needs a multidisciplinary approach combining theoretical and computational material science, solid-state physics and chemistry, and electronic device and circuit design and technology. These synergies are reflected in the collaboration between the teams led by Professors Nicola Spaldin (Materials Department, ETHZ) and Adrian Ionescu (Electrical Engineering Department, EPFL).
