Abstract:Wireless communication is today considered as a disruptive technology. Indeed, even if wired systems can easily achieve 100% of reliability, it induces high amount of wiring, which has non negligible impact on the mass and so on the lifetime. In order to save time and planning, wireless communicating sensors appear as a wiring optimization, allowing rapid installation without modification of the general electrical network. But such systems need embedded energy. In order to demonstrate the validity of wireless technology concept adapted to various environments including the space, the aeronautic or the building ones, the developments of miniature & autonomous Li-ion batteries are described in this paper. Their prototypes performances in space, aircraft flights, cold environments or harvesting conditions are discussed. New chemistries for higher energy density, above 250Wh/kg, or low temperature operating electrolytes, below -20°C, are also introduced.
