Presentation of the research activities of ZeroPower

Energy harvesters are realized thanks to a dual band rectenna (0.9 GHz, 2.45 GHz) able to power a 5μW digital clock.  The system is developed on a conformable substrate (Kapton) allowing a better adaptation on the environment and an improvement in terms of portability, weight, and manufacturing cost. As a continuation the team is now focusing on developing metamaterials based antenna for WBAN applications and hybrid energy harvester coupling RF and piezoelectric

The studies concern the conception of photonic crystals (microwaves domain) and electromagnetic behavior of metamaterials

Research focuses on the design of specific equipments for the monitoring of the environment (vegetation, soil, water) using in situ, continuous and non-intrusive electromagnetic measurements. As examples, the data collected makes it possible to improve knowledge of global warming (study of permafrost) or to study the effects of water stress on vegetation. This research also makes it possible to improve the permittivity estimation models of natural environments, essential for the data treatment of space remote sensing missions (SMOS, BIOMASS).

The MIM team has recognized expertise in microwave measurement tools associated with physical propagation or electromagnetic characterization models. Dielectric spectrometry allows to deduce from permittivity other physical quantities such as humidity, salinity or the density of a medium for the nondestructive testing. The team has several measurement and analysis benches over a wide spectral range, from DC to 110 GHz, to characterize a wide range of materials (homogeneous, heterogeneous media, conductive polymers, ceramics, carbon nanotubes, hydraulic concrete, natural media).

Numerous research results are stored in a database call CASEMAT (CAractérisation et Simulation Electromagnétique de MATériaux) accessible at http://casemat.ims-bordeaux.fr/ .

Results of measurements and simulation/modelling of wave/material and wave/structure interactions are stored  (70,000 data). This tool is useful to share our results with other researchers in the framework of collaborations. Free but limited access is allowed on a guest account (login: invite, pwd: invite).

REMPOWER project selected as a part of the Pathfinder challenge portfolio

The REMPOWER project is one of the 43 selected projects among 368 submitted eligible proposals under the EIC Pathfinder Challenges call for cutting edge research projects.

REMPOWER project (REctenna in Millimeter-Wave frequency range for High-POWer Energy Reception) aims at achieving breakthroughs in In-space solar energy

LINK to the EIC Pathfinder Challenges results

With its Pathfinder scheme, the EIC supports the exploration of bold ideas for radically new technologies. It welcomes the high-risk/high gain and interdisciplinary cutting-edge science collaborations that underpin technological breakthroughs.

EIC Pathfinder projects benefit from interactions with EIC Programme Managers and can receive additional funding for testing the innovation potential of their research outputs or for working across projects for portfolio actions. In addition, promising results can receive substantial follow up funding through the EIC Transition scheme to create a commercial venture or use the Fast Track scheme to access the EIC Accelerator to bring innovations to the market.
