| 摘要 |
<p>The invention concerns a component comprising a sealed cavity (9) wherein is arranged the unprotected power source (4-7), consisting of a micro-battery or a micro-supercapacitance. Any penetration of ambient air into the sealed cavity causes, by oxidation, the destruction of the power source, thereby making the component inoperative. The cavity (9) can be under vacuum or filled with an inert gas. A pressure sensor can be arranged inside the cavity and detect a pressure variation inside the cavity to make the component inoperative when the pressure variation exceeds a predetermined threshold. The cavity (9) can be closed with a cover (10) or filled with a filling material consisting of silicone resin, thermosetting resin, polymer, epoxy resin, fusible glass or a metal selected among indium, tin, lead or alloys thereof.</p> |
