Smart use and management of energy is a fundamental requirement for the sustainability and maximum efficiency of systems such as the “Internet of Things”.
Our research enables nanodevices and integrated systems with ultralow energy consumption, minimising all the parasitic energy (electrical, thermal, mechanical) losses which make devices power-hungry and less performant. Low energy consumption needs to be complemented with efficient energy storage and an appropriate system design. Nanomaterials like graphene and novel 2D materials are key enablers.
Some of our current areas of research are:
- 2D materials and nanofabrication;
- Low- power consumption electronics;
- low-loss plasmonics;
- low-damping resonant MEMS for molecular recognition;
- efficient on-chip energy storage.
The INSYS Lab is associated with
- direct synthesis of functional nanomaterials (particularly graphene and other 2D materials) on semiconductor substrates
- compatible integration with semiconductor fabrication (materials, areas, processes, temperatures, etc.),
- quality, electrical and mechanical reliability for large -scale fabrication (devices, interconnects and packaging).
- System-level design
- Highly interdisciplinary approach (Materials Science, Physics, Chemistry, Mechanical and Electronic Engineering).
We were recipient of a Global Innovation Award at the World TechConnect Summit in Washington DC, USA, 2014 “Processes enabling low cost graphene/silicon carbide MEMS”.
