MATERIALS FOR ENERGY

F

Advanced materials, components & processes for integrated autonomous micro-power sources

The increasing demand for autonomous micro-systems in the fields of IoT, healthcare, defense, etc is raising the need for miniaturized power sources. Combinations of energy harvesting and energy storage micro-devices open the way to optimized, possibly ‘perpetual’, energy supply. The symposium will focus on new material developments & material processing related to these micropower sources, their design and integration on shapeable substrates, with the objective to gather scientists working in complementary areas.

Scope:

The availability of efficient energy sources has always conditioned the development of off-grid electronic devices. In return, the emergence of new applications has always been a motivation for the development of new energy supply solutions. While the number of applications of stand-alone sensors and active RFID tags networks is booming, the need for well-adapted micro-power sources in terms of autonomy, power, shape/size or resistance to the surrounding environment is becoming essential. Extended autonomy is expected to be provided by harvesting energy from different sources in the local environment by means of specific miniaturized transducers: photovoltaic cells, thermo-, piezo- or magneto-electric micro-generators, micro-biofuel cells… Due to the intermittent, unpredictable and possibly unsuitable character of the electric signal delivered by these micro-harvesters, the interposition of an energy storage micro-device such a microbattery or a micro-capacitor able to absorb and to deliver the appropriate energy profile might be quite compulsory. The achievement of a suitable integrated micro-power module (few cm2¦3 <), optimized for a given application, is certainly conditioned by the synthesis and the shaping of high performance functional materials, possibly nanostructured, and specific designs for each component and device, but is an even more complex challenge when constraints related to maximized integration, coupling of multiple transducers, device flexibility, additive manufacturing processes or reduced production costs have to be considered simultaneously. The symposium will therefore address advanced solutions in terms of functional materials, (micro-)manufacturing processes, integrated design and coupling of energy components for stand-alone micro-energy modules, with a particular, but not exclusive, interest for flexible devices.

Hot topics to be covered by the symposium:

  • Triboelectric micro-generators
  • Piezoelectric micro-generators
  • Thermoelectric micro-generators
  • Miniaturized photovoltaic cells
  • Micro-batteries
  • Micro-supercapacitors
  • Micro bio-fuel cells
  • Thin film materials for energy
  • Advanced materials and processes for integration on flexible substrates
  • Printed electronics dedicated to stand-alone micro-systems
