Abstract: Embodiments of the invention include adhesive electrode sets and related methods. In an embodiment, the invention includes an adhesive electrode set. The adhesive electrode set can include a first pad, a first electrode, a first electrical contact, a first conductive lead, a second pad, a second electrode, a second electrical contact, a second conductive lead, a flexible strip, and an adhesive material. The flexible strip can include a fold. The flexible strip can be configured to allow the distance between the first pad and the second pad to increase through flexion of the flexible strip. In an embodiment, the invention includes an analyte receiving test patch. The analyte receiving test patch can include a skin contact layer, a wick, an absorbent layer, a barrier film layer, and an adhesive frame. Other embodiments are also included herein.

Abstract: Electrical connector apparatus optimized for biomedical applications. In one embodiment, the connector apparatus comprises a low-cost simplified device having a unitary conductor element adapted to interface with an electrode terminal such as used in impedance cardiography (ICG) or electrocardiograhy (ECG). The unitary conductor is shaped so as to provide a high degree of electrical performance and signal stability, and also be highly reliable. The simplified structure of the connector (including the use of the unitary conductor element) allows it to be manufactured for very low cost, so as to be disposable if desired. Methods of manufacturing and operating the connector are also disclosed.
