MULTILAYER CONDUCTIVITY SENSOR4

摘要

A contacting -type conductivity sensor (100, 200) is provided. A first insulating layer (116) has a proximal surface (102) to contact a liquid sample, and an opposite, distal surface (122). A plurality of electrodes (104, 106, 110, 112) is disposed on the proximal surface (102) of the first insulating layer (116). Each of a plurality of conductive vias (118) is electrically coupled to a respective one of the plurality of electrodes (104, 106, 110, 112), where each via (118) defines a conductive path from the proximal surface (102) to the distal surface (122) of the first insulating layer (116). A plurality of traces is disposed adjacent the distal surface (122) of the first insulating layer (116), and each of the plurality of traces is electrically coupled to a respective one of the plurality of conductive vias (118). A plurality of conductors (132) is provided where each conductor (132) is electrically coupled to a respective one of the plurality of traces. A cover layer (130) is coupled to the first insulating layer (116).
