▎ 摘　　要

NOVELTY - The nose has a screw (3) with a gasket (4) and a nut (11). A polytetrafluoroethylene (2) containing polyteterfluorethylene tube (1), stainless steel clamp (8), top part chamber (5), a bottom chamber (9), LIGIE sensing array (7), and rubber ring (6). The LIGI sensing array comprises a flexible polyimide film, interdigital electrode, namely a flexible LIGIGIE, composed of interdigital and lead engraved on the film, and an LIGIF silver conductive area formed by coating conductive silver paste at the lead position of the flexible LigIE. The bottom chamber is an organic glass plate, one surface is adhered with a kraft paper, organic glass board on one side of the k. The size of the PI tape after cutting is matched with the flexible LIGIE, and the PI tape corresponding to the flexible LIGIE interdigital area is removed. USE - Micro-cavity integrated electronic nose used in volatile gas sensing. ADVANTAGE - The micro-cavity integrated electronic nose does not need any glue water bonding and the LIGIE sensing array and the contact is conductive without welding, which effectively ensures that each component can be simply replaced, and is easy to be prepared in batch, and the volume is small and plug-and-play. DESCRIPTION OF DRAWING(S) - The drawing shows an schematic view of the micro-cavity integrated electronic nose. 1Polytetrafluoroethylene tube 2Polytetrafluoroethylene joint 3Screw 4Gasket 5Top part chamber 6Rubber ring 7LIGIE sensing array 8Stainless steel clamp 9Bottom chamber 10Bending needle 11Nut
