    • An oxygen measuring sensor is proposed, having a pump cell (20) with outer and inner pump electrodes (17, 19) disposed on a solid electrolyte (11) which conducts oxygen ions, of which the inner pump electrode (17) is exposed in a diffusion conduit (15) to the gas to be measured. A further electrode (18) of a measuring cell (21) is disposed in the diffusion conduit (15) behind the inner pump electrode (17) in the direction of diffusion, at which a partial oxygen pressure, which lies at least approximately in the vicinity of lambda=1, can be set by means of the pump cell (20), so that the pump cell (20) operates outside of the limiting current range of the current/voltage characteristic curve.

    • A sensor element for determining concentration of at least one constituent of a gas mixture operates on an electro-chemical measuring process and includes a gas measuring chamber; a pair of electrodes and an electrode chamber located between the pair of electrodes; and a diffusion conduit adjoining the electrode chamber and having a gas input which connects with the gas measuring chamber, having a gas output which connects with the electrode chamber, and having at least one cross-sectional area including a height, w, and a length, L, which height, w, has a preselected minimum value, and which length, L, has a value which is equal to or greater than the preselected minimum value of the height, w. The constituent of the gas mixture has a mean free path length through the sensor element, the gas measuring chamber has a cross-sectional area including a height and a length each of which are at least as large as the minimum height, w, of the diffusion conduit, and the height, w, of respective ones of the at least one cross-sectional area of the diffusion conduit is at least a multiple of the mean free path length of the constituent of the gas mixture to be measured. Advantageously, substantially only gaseous phase diffusion occurs when the predetermined minimum value of the height, w, is at least a multiple of a minimum value of the mean free path length for the gas constituent measured.

    • An anisotropically conducting adhesive includes an adhesive base material; and conductive particles which are dispersed in the adhesive base material and which have provided on the surface of the conductive particles a separating agent comprised of at least one ligand which is selected from the group consisting of triphenylphosphine and propionic acid, which decomposes during use of the anisotropically conducting adhesive in an adhesion process and which is non-polymeric. A method for producing a bonded, electrically conductive connection between a plurality of strip connectors includes (a) providing the foregoing anisotropically conducting adhesive; (b) positioning strip connectors on opposite surfaces of the anisotropically conducting adhesive; (c) applying pressure to the anisotropically conducting adhesive and the strip connectors; and (d) decomposing the at least one ligand of the anisotropically conducting adhesive.
