    摘要: A process for preparing a solid electrolyte or a composite electrode incorporating a solid electrolyte, configured for an electrochemical system, may involve: (i) synthesizing, in a solvent medium, at least one (co)polymer by ring-opening (co)polymerization (ROP) of at least one 5-8-membered cyclic carbonate and, optionally, of at least one 5-8-membered lactone, catalyzed by Brønsted superacid(s) and initiated by compound(s) comprising hydroxide group(s); (ii) adding to the reaction medium a sufficient amount of an alkali metal or alkaline earth metal hydride, e.g., LiH, to neutralize all the catalyst and obtain an alkali metal or alkaline earth metal salt and to protect the terminal hydroxyl group(s) of the (co)polymer(s); (iii) optionally adding to the mixture from (ii) salt(s) of the alkali metal or alkaline earth metal, e.g., a lithium salt; and (iv) forming a solid electrolyte by evaporation of the solvent medium or a composite electrode incorporating the solid electrolyte.

    摘要: An electromechanical microsystem including an electromechanical transducer, a deformable diaphragm, a first cavity hermetically containing a deformable medium keeping a substantially constant volume under the action of an external pressure change and a second cavity. The deformable diaphragm forms a wall of the cavity and has at least one area freely deformable elastically. The free area also forms a wall of the second cavity. The electromechanical transducer is configured so that its movement depends on the external pressure change, and vice versa. A change in the external pressure in the first cavity induces a variation of the volume of the second cavity, or vice versa. Thus, the proposed electromechanical microsystem enables gripping of an object obstructing the opening of the second cavity and forms a microbarometer capable of converting at least one ambient pressure change into an electrical signal.
